Discover The Importance Of Moisture And Temperature Sensors


Unless you are an experienced factory operator or an industry manager, there are great chances that you believe that the coffee you pour in the coffee machine every morning smells so delicious just because you have stored it in a dry and dark place or that the breakfast cereals that your children enjoy so much are crispy because you always remember to close the plastic bag carefully. And although these two daily routines are indeed important, coffee smells delicious and your cereals are crispy and your potato chips are not humid because they were also well taken care of during their specific manufacturing processes.

Factory operators and industry owners and managers are well aware of the fact that their main responsibility is to produce products that their customers are eager to purchase over and over again because of their high quality and to keep up with the ever increasing industry standards. In some occasions, industry workers can ensure that the products they are manufacturing are of good quality or that they comply with the standards quite easily because the aspects to be monitored can be effortlessly distinguished or measured with their naked eyes or hands. However, in most occasions, they need to rely on specific and sophisticated equipment called process sensors in order to make sure that the temperature or humidity of the item being made are the correct ones.

Process sensor is the generic name given to moisture analyzers and temperature sensors, which are sophisticated instruments that are used in wide variety of industries. Amongst them we can mention the animal and pet food industry, breweries, chemical and pharmaceutical labs and wood factories.

Moisture sensors are also usually referred to as hygrometers or humidity analyzers and they are situated along different steps of the manufacturing process. They help factory operators be sure that barley used to make beer is not stored wet, that potato chips are dry enough before entering into the packaging process and that coffee beans are not packed wet so that they taste and smell sour when consumed. As not all manufacturing processes are the same or require the same level of humidity in every step, factories usually place different hygrometers to keep a close monitoring of the humidity level all throughout the manufacturing procedure. Each time, a sample is taken and weighed. Then it is introduced into the moisture sensor and dried out. After that it is weighed again and the difference in weight lets the operators know if the humidity level is acceptable or if any change needs to be made.

Temperature sensors are mainly used in laboratories where chemical compounds may lose their valuable properties if they are exposed to very high or low temperatures.

Moisture Sensors Can Prevent Foundation Damage


Home owners are well aware of the fact that preventing foundation damage is of utmost importance to ensure the integrity of their property. If the foundation of their home is damaged, then the stability and resiliency of the property is endangered and the lives of all the people living in it is put at risk too.

Apart from a bad constructed foundation, one of the most common issues that this basic part of our homes can suffer from is water damage. Either we live in an extremely wet area and the soil gets extremely wet and takes a lot of time to dry out or our house draining system is clogged so that it does not work properly. No matter the reason, if the house foundation gets wet, we may start finding humidity stains on walls and moss and fungi on ceilings and corners.

Leaking pipes are also a common cause of foundation problems. Many a time, problematic pipes can be easily detected and repaired by a professional plumber. But other times they are really very difficult to detect and, when we do, it is already too late. Either the damage in our piping system is too extensive or we discover overnight that our basement has turned into our own ocean.

Fortunately, technology advancements have come to make the life of home owners much more valuable and easy. Now, there are instruments that can accurately help home owners detect an excess of humidity somewhere in their house so that they can immediately try to solve it.

One of the most interesting technical advancements that have appeared in this sense are humidity sensors. These devices are also popularly referred to as moisture analyzers or hygrometers. These are devices that are extremely sensitive to humidity and that can accurate measure the relative humidity present in a certain environment and report the values to the user. Thus, he can decide if they are within acceptable ranges or if they need to be somehow adjusted. In the case of a home owner, if according to the hygrometer the environment is too wet, he can then decide to call a plumber to do a major check up. Moisture sensors can be placed in basements so that any unusual level of moisture can be detected. Moisture sensors are really easy to calibrate and to operate as they are simplified but accurate versions of the instruments used for industrial or manufacturing purposes.

Temperature-Humidity Sensors in Pharmaceutical Testing


Pharmaceutical Products fall under some of the most stringent regulations of any manufactured good out there. Product testing against varying environmental conditions need to be recorded using both accurate temperature-humidity sensors and reliable data logging software.

Such process control testing is referred to as stability testing because test materials are analysed for any degradation or significant physical changes throughout various temperature and relative humidity settings.

The stability of a pharmaceutical product is a measure of its ability to resist deterioration during the period within which its properties and characteristics can be expected to remain with certain limits. All articles intended for use in diagnosis, mitigation, treatment of prevention of disease undergo some form of testing, often multiple times in the product development cycle, from drug development to package selection. ?

Temperature-humidity sensors are just one portion of a stability testing system. Older more cumbersome systems make use of large environmental chambers to contain all the test samples. The disadvantages of environmental chambers are that you can only test the samples for one temperature and relative humidity setting in equipment that takes up a lot space and has high running costs. Modern bench-top stability testing units or "small scale stability testing units" allow for many different sensor readings to be logged at the same time in a relatively small amount of physical space. ?

Calibration requirements for temperature-humidity sensors ?

Generally speaking temperature sensors require less calibration as they tend to maintain better accuracy levels. The humidity sensor will require more frequent calibration as accuracy can shift at higher temperature ranges. This is not a substantial problem if the product in question needs to be tested for relatively low temperature ranges but is the control process requires cycling over a large temperature range then a robust temperature-humidity sensors with frequent calibrations is recommended.?

When purchasing new and used units it is also advisable to ensure that calibration certificates are provided with the purchase (Don't forget to ask if the certificates are traceable and for which regions they are valid). A calibration certificate should be a minimum requirement to conform for international standards. ?

Various international validation requirements also regulate the way electronic signatures are used, how electronic data is stored and other computerized system requirement affecting Stability Testing. So not only must your sensors be compliant but also any associated data storage units. Those interested in further reading would do well to reference the FDA 21 GMP's Eudralex volume 4 requirements.

Install A WiFi Sensor to Get Accurate and Fast Measurement of Temperature


Do you run a hospital, blood bank, pharmacy, food services, or a data center? Then, perhaps you have already seen how temperature plays a huge role maintaining the quality of medical products such as medicines, blood products, and other pharmaceutical goods. Moreover, in hospitals, increased humidity can create numerous health problems and make patients feel uncomfortable. So, to avoid all these things you need to control the temperature appropriately. That is why you need to keep a constant track of the temperature.

Though, humidity in air is necessary to some extent, but if it exceeds the recommended level, medicines and blood products can get damaged. Even breathing and indoor plants can form moisture. Moreover, we unknowingly produce moisture by various water based activities like washing, cleaning, bathing, cooking, and so on. All these activities can increase the moisture level. Apart from that, medical instruments can produce a lot of heat as high voltage electricity is flowing through them continuously. So, ultimately, the heat is affecting the normal temperature of the room. This is why temperature must be measured accurately. And, the best way to do this is installing WiFi sensors to measure the level of humidity.

WiFi sensors are used to measure and get the accurate reports of relative humidity (RH) present in the air. These devices can be installed with heating, ventilating, and air conditioning units (HVAC). It will convert the report into digital reading to help you get the precise measurement of the moisture present in the air. These devices are widely used in health departments, hospitals, multi-location medical facilities, and many other health care services. Because of their effectiveness and accuracy, they can measure temperatures down to -200' C. In case it detects a poor temperature condition, it will alert you instantly along with the necessary actions you need to take to improve the air quality.

A quality WiFi sensor have the following features:

* They are battery powered. So, in case there's a power cut and you don't have immediate backup, your WiFi sensor won't stop working.

* The sensor nodes of WiFi sensors communicate directly with Industry Standard Access Points. That means, more accuracy without wasting any time.

* You don't need to attach any other devices with the WiFi sensors. So, that eliminates the hassle of purchasing expensive devices like routers, hosts, repeaters, and receivers.

* These devices are capable of using all types of WPA, WPA2, and WEP encryption.

Remember, your first priority is to get in touch with a reputed company selling WiFi sensors that have all the features mentioned above.

The Workings of the Humidity Calibration Equipment


The art of the humidity calibration has been a complex system to many, and also that relative humidity is well known to be the most complicated of physical quantities to calibrate. The reason for this been, is that before you are able to calibrate humidity, you have to ensure that the area is indeed stable to get high accuracy.

The correct pressure calibration equipment has to be in place in order for you to get this done correctly. This can lead to be a complicated matter if you are tempting to do this outdoors. There are various methods with the humidity calibrators that you can choose from, and every humidity calibration methods does need temperature uniformity to get an exact measurement of the temperature that you are given.

Most of the humidity calibration equipment is delicate to ambient temperature and to the relative humidity. Depending of the type of maintenance that is given, there are certain tolerances as well as calibration standards that have to be kept, if not so, there could be doubts in the results. That is why it is important that you do keep the humidity as well as the temperature as this is what is reported on all calibration certificates. The air handling systems that are been used for the use of environment control, and this is also, where the humidity calibrators work, and the monitoring of the devices ensures that the systems does operate accurately.

This is also to ensure that all parameters are kept at reasonable limits, and this is important to the use of any laboratory. Laboratories that are located throughout the world, make use of mechanical humidity as well as temperature charts for more than a few years, and up until now there has been the digital recorders that has made things so much easier for them. This means that the recording of all data could be done for longer periods at a time and you would get the most accurate results from this.

There are two sensors that are on the display unit of the humidity recorder, and they both have their very own sensing devices for the seeking of any temperature elements. This means that the monitoring of relative humidity and temperature would be accurate in two different locations at the same time. The sensor also has an analog to digital converters. The measurements are then done in digital format and is passed on from the display to the sensor unit. This means that the sensor unit is the sole accuracy provider. The only division of this unit that bears any type of importance is by all means that senor unit. The sensor units calibration adjustments the setting of digital parameters that are able to be stored in a non volatile memory and this is located in the sensor units.

You should ensure that you do indeed have the know how when it comes to the humidity calibration, as this is highly important when you measure the temperature as well as relative humidity, when you are using the torque calibrator, you will have errors to deal with in the end.

Wine Storage: How Humidity Affects Your Wine


When you think about wine storage, one of the last things to cross your mind is how will humidity affect it. Most people blindly store their wine wherever they can find a place for it, whether it is in the refrigerator, downstairs in the basement bar, or in a kitchen cabinet. However, what many people fail to realize is that both temperature and humidity have large effects on wine. This means that wine storage anywhere you can put it can truly ruin the taste and quality.

The fact of the matter is that thought does have to go into storage. In all honestly wine is probably of the hardest liquids to store properly as it isn't something you should put wherever you have space. Though there are all sorts of information available on wine storage, there are so many different opinions and answers that it can be hard to decipher which one is most accurate.

If you know anything about wine, you may be well aware of something we call wine coolers. Wine coolers are storage units made specifically for wine. This means that there is a set temperature, humidity level, and a set amount of light for each wine cooler. Wine coolers are one of the most effective and easiest means of wine storage.

When it comes to storage, humidity plays a large role simply because humidity is what is used to seal and cork the bottle. Humidity is needed so that the cork holds the bottle closed tightly as to prevent spillage. At the same time too much humidity can ruin the cork as well as the bottle's label, so it's important to ensure your wine is stored at the right humidity.

If the cork becomes damaged or deteriorated, the solid seal is broken and the wine will start to allow for oxidation. This will cause any wine to become extremely bitter as the oxidation will turn the wine into vinegar.

How do I know which humidity is correct?

If you're storing your wine bottles in a wine cooler, it isn't as important to pay attention to the humidity levels as the wine coolers are made in such a way to create a pretty ideal environment to store wine in. if you do not own a wine cellar, you'll want to find a place where you can store your wine within a 50-70% humidity level.

You will do more damage to your wine when the humidity level is too low. If the humidity level is too high you simply face a ruined wine bottle label. Of course, it is best if you can store your wine within in the 50-70% range to ensure that your wine tastes as good as it was meant to. To determine the humidity of an environment you'll need to find a hygrometer or a humidity sensor. Both will be able to give you the humidity reading within any environment.

How A Humidity Sensor Can Help You Improve the Air Quality


What is humidity?

Humidity is the total amount of water vapor or moisture present in the air. You, your family members, and even your pets produce moisture at the time of breathing. Did you know, even your indoor plants can create moisture? Moreover, we use water in various indoor activities like bathing, showering, washing clothes, cooking, and dish washing. All these can form moisture, that, if not controlled or measured properly with the help of a humidity sensor, can cause serious health problems. And, if you run a health center like hospital, blood bank, and pharmacy then you keeping track of the temperature is an absolute necessity.

When does humidity becomes a problem?

Certain amount of humidity is required for the comfort and health of you and your family members. However, too much or too little amount of humidity can create a lot of problems. Such problems generally becomes intolerable when all the windows and doors are closed and the indoor air cannot circulate properly.

How a humidity sensor can help

It is a device that is used to measure and get the report of the relative humidity present in the indoor air. If you or any of your family members suffer with illness affected by humidity, then you can consider buying a measurement device as a part of your heating, ventilating, and air conditioning (HVAC) systems. Apart from that, they can also be used in wine cellars, cars, commercial HVAC systems, and meteorology departments to predict and report weather.

How does it work

Such devices sense relative humidity (RH) and measures moisture and air temperature. Wondering what is RH? Well, it is the ratio of the total moisture present in the air and how much temperature the air can hold. Generally, the warmer the air gets, the more moisture it becomes. That is why relative humidity or the ratio fluctuates in temperature. A humidity sensor will sense the ratio and convert it into digital reading to show the amount of moisture.

What are the options available

However, there are different types of humidity sensors available in the market but not all of them can provide precise measurement of temperature and humidity. Moreover, if you do not want to get into the hassles of wires and huge devices, then you should consider buying a compact WIFI device for your requirements. These devices are accurate, small in size, and affordable as well.




Want to buy superior quality humidity sensor from a company that is an industry leader and is renowned for manufacturing WIFI Sensor products? Then, SensoScientific, Inc. is the name you should trust.

Exploring the Technology of Humidity Sensors


Science and processing technology rely on humidity sensors as part of control systems in a variety of applications. Many people are aware of the relative humidity number reported by the local weather reporter on TV. While this helps the average citizen prepare for his day, it is only one very small reason for the existence of sensors to measure humidity. Humidity has impacts on a wide range of industrial and scientific processes and makes a difference in everyone's daily lives. This short article will examine the technology and uses of humidity measurement.

The basic definition of humidity is the water vapor content in a gas such as air or nitrogen. Notice this refers to water vapor - not water in any form. Water existing as a mist or ice crystal in air is not within the definition of humidity. Also, humidity is discussed in various terms depending on how the measurement is made and used. Within certain ranges it is possible to calculate the equivalent measurement in different terms, such as converting relative humidity measurements to dew point temperatures.

Three often used measurement terms are relative humidity, dew point and absolute humidity. Each of these is measured differently and used differently in process controls or data recording applications. Humidity measurement methods have evolved tremendously over the decades.

Early scientists realized human hair changed when water content in the surrounding air changed. This led to mechanical devices that indicated humidity by the changes in a strand of hair. Both human hair and horse hair were used to power indicators or chart recorders. Materials technology provided nylon and other synthetic fibers that were more predictable and easily calibrated. Today, relative humidity sensors are solid-state electronic devices with lower cost and greater robustness.

Dew point is the combination of temperature and gas pressure at which water vapor begins to condense into liquid. Most people understand this in weather report terms but it is an important factor in many scientific calculations and processes outside of weather. Early dew point measurements used chilled mirror technology which was both expensive and temperature limited. Modern electronic dew point sensors are accurate down to -40degrees F.

Absolute humidity is the precise measurement or calculation of the mass of water vapor in a given volume of air or other gas. (Expressed as grams per cubic meter or grains per cubic foot) This is the most useful measurement for a variety of applications. One interesting application is in drag racing. The grains [of water in the ambient air] number is used by all race teams in setting up their racing engines. Modern electronics can measure absolute humidity at temperatures greater than 200 degrees C in almost any environment.

Sometimes process stability problems are related to humidity changes in the process environment. Monitoring humidity can provide clues why results are not consistent. Painting quality can suffer when humidity changes and the process is not adjusted to compensate. The wide range of sensors on the market today assures coverage for any perceivable application.

Humidity sensor manufacturers can deliver accuracy, robustness, size, and cost to meet just about any scientific or technological requirement. Some online research is sure to reveal a variety of options for any application. This article should provide just enough information to make your research more effective.

8 Steps to Measure the Relative Humidity in Concrete According to the ASTM Standard


Practical advice for measuring humidity

The most common source of error when measuring relative humidity is a difference between the temperature of the probe and the temperature of the environment. At a humidity condition of 50 % RH, a temperature difference of 1 °C (1.8 °F) typically results in an error of 3 % RH on relative humidity.

It is good practice to monitor the display of the moisture meter for temperature stability. The probe should be given sufficient time to come to equilibrium with the environment to be measured. The larger the initial temperature difference between the probe and the environment, the more time is required for temperature equilibrium.

In extreme situations, condensation may occur on the sensors when the probe is colder than the environment. As long as the humidity / temperature limits of the humidity sensor are not exceeded, condensation does not alter the calibration of the sensor. However, the sensor has to dry out before it can provide a valid measurement.



Step 1: Check the correct functionality of the instrument and probe using the humidity standard tube.

Step 2: Concrete floor slab and air space surroundings must be at service temperature / humidity for at least 48 hours.

Step 3: Define numbers of test holes

Step 4: Define depth of test holes

Step 5: Drill and prepare test holes

Step 6: Wait 72 hours for moisture equilibrium

Step 7: Measure

o Insert in-situ probe into sleeve

o Wait for temperature equilibrium

o Check for stable values



Step 8: Report all necessary information

Residential Humidity And Temperature Sensors


Have you ever imagined that it would be possible for you to keep the humidity and temperature of your house under control independently of how wet or dry it is outside or of how cold or hot the weather is? Believe it or not, this is now possible for many home owners thanks to technological advancements that have made ordinary industrial devices more compact and affordable for domestic use.

Over the last years, more and more home owners are using humidity and temperature sensors to keep the moisture and temperature levels of their properties at comfortable and healthy levels. These devices, which are widely used in industrial facilities to ensure that the manufacturing process occurs seamlessly and according to quality standards, are becoming more and more common for residential use.

At first, humidity sensors, usually referred to as hygrometers or moisture analyzers, were used in family groups in which a member suffered from allergies or some kind of pulmonary disease that made him or her especially sensitive to allergens or changes in the humidity conditions present in a room. Thus, with a moisture sensor it was easy to establish a safe level of humidity and make immediate amendments to it every time it was necessary.

Little by little these devices became more popular as home owners assessed their advantages. By installing one in their basement, it was easier for them to detect leaking pipes that would cause a disaster if left unattended or discovered months later. These humidity analyzers are extremely sensitive instruments and, fortunately, they are easy to calibrate and operate. As they are precise instruments, the information they provide can be trusted thus ensuring that the comfort and quality of your home is ensured.

Temperature sensors are also very popular as they help family groups make a better use of their heaters and air conditioning devices and, as a consequence, save money on electricity. Temperature sensors can be connected to the heaters or air conditioners so that whenever this thermometer detects that the temperature is lower or higher than expected, the heating or cooling instruments are turned on until the previously set up temperature is reached.

Home owners can place temperature sensors in each room of their house as they can be set up individually. Just as humidity sensors, they provide accurate and trustworthy information that helps every member of the family to be in a room as comfortable as they want it.

What are you waiting for? Buy one of these devices, or both of them, for your house and enjoy the home of the future.

An Introduction to Humidity Sensors


In scientific and industrial environments humidity sensors are highly appreciated devices as part of their control or monitoring systems as they allow factory operators and scientists make sure that they are operating with chemical compounds or other kind of elements in an environment that complies with the adequate levels of humidity.

There are a wide number of applications where humidity sensors become useful. Humidity can have a serious impact on chemical and industrial processes, ruining hours and hours on end of production and scientific efforts and this is why these instruments are so valuable.

Humidity is the content of water vapor in air and we are quite used to learning about it every morning as we listen to the weather forecast before going to work. Just as an excess of humidity makes it difficult to keep our hair straight and we suffer from frizz (curly haired men and women know what I am talking about), in laboratories and industrial environments such as pet and human food industries, leather industries, coffee bean grinding industries and beer manufacturing an excess of humidity can be really serious. And just as we cannot tell exactly how wet it is outside just by popping our heads out of the window, factory operators and scientists need to rely on humidity sensors or hygrometers to know if the place where they are manufacturing medicines, beer, potato chips, grind coffee, pet food, breakfast cereals and so on is dry enough. Hygrometers are extremely sensitive devices that can tell quite accurately if there is a need to do some kind of adjustment to the humidity levels.

Industries and laboratories usually have more than one humidity sensor installed in their premises as each step of the manufacturing process may require precise levels of moisture. At certain stages of the manufacturing procedure a sample is taken and weighed. Then it is introduced in the moisture sensor where it is dried up. This can take several minutes or a couple of hours depending on the size of the sample and what has to be measured. Once dried, the sample is weighed again. An operator compares the two weights in order to know the water content in the initial sample. If the result obtained is within acceptable levels, the process continues but, if any kind of correction or adjustment has to be made, he does it immediately so that the manufacturing process is not altered.

The Gardener's Dream: Moisture And Temperature Sensors For Your Greenhouse


Having a greenhouse is every gardener's dream. However, unless you live in a large house that is surrounded by a large green area where you can build your own greenhouse odds are that your only chances of enjoying one is when you visit the plant seller.

Greenhouses provide the perfect environment to grow different kinds of plants and flowers, especially the most delicate ones that require specific levels of humidity in order to grow properly and are extremely sensitive to drastic changes in temperature. Some greenhouses are very large and others are smaller, but they all have that distinctive atmosphere and smell that invite us to travel, at least with our minds, to foreign tropical forests.

If you are lucky enough to have a glass building you can turn into a greenhouse, you will find this article particularly useful as we will discuss two gadgets that will make it really easy for you to keep the temperature and humidity in the environment within perfect levels: a moisture sensor and a temperature analyzer.

Moisture sensors are also popularly referred to as humidity analyzers or hygrometers. They are extremely sensitive and technical devices that allow professional and amateur gardeners to ensure that the plants and flowers that they keep in their greenhouse are in an environment that provides them exactly with the humidity they require. These instruments are really accurate and they can be adjusted to the needs of a particular plant species. It is even possible to connect the moisture analyzer to the irrigation system so that plants only receive water when they need it and therefore they are not exposed to unnecessary watering.

Professional greenhouses usually have more than one humidity analyzer and the gardener monitors the different devices from a central computer and makes automatically all the necessary adjustments.

Temperature sensors or analyzers are thermometers that help professional and amateur gardeners be sure that the plants that they have growing in their greenhouse are kept under the correct temperature. As you probably are well aware of, seeds and plants are extremely sensitive to temperature changes and they grow healthier and better if they are not exposed to drastic changes in temperature. In addition, some tropical plants need certain temperatures in order not to wither and even a drop of a few degrees can make them wither.

You can buy your moisture and temperature sensor over the Internet or in shops devoted to professional gardening.

What is a Humidity Sensor and How is it Useful?


Humidity sensors are used in homes as part of the HVAC (Heating, Ventilation, and Air Conditioning,) as well as in office buildings and industry. They are used in places that are affected by high and low humidity that requires a set constant humidity to be maintained. A humidity sensor, also referred to as a hygrometer, is a device that measures the humidity in the air. The humidity sensor monitors the electrical changes in relation to the quantity of humidity in the air. It is used to control such machines as air conditioners, humidifiers, and dehumidifiers by adjusting to the changes in the level of humidity in the air.

Hygrometer are beneficial for people who suffer from health conditions that are aggravated by high humidity. As well, a person with allergies or asthma can use a humidity sensor because low humidity can aggravate these conditions and too much humidity can cause the growth of fungus, bacteria, mold, and mildew which can also aggravate these conditions. They are also useful for people with wine cellars who want to maintain a constant temperature and humidity so wine does not spoil. As well, hygrometer are useful for storage of valuable items such as antiques which can be damaged if exposed to moisture. The sensor mechanism of the humidity sensor detects the electrostatic changes in the air as the humidity in the air around it changes.

The benefit of these sensors in industry are they allow for accurate measurements and recording of humidity data. The data loggers can be used for real-time monitoring and sends an alert if there are sudden changes. Once the sensor picks up the changes, the measurement is then converted into humidity readings and recorded in a data logger. The changes in voltage are converted into digital readings showing the amount of moisture in the air. There is the choice of using a couple of data loggers in one application or numerous data loggers for monitoring broadly dispersed locations. It is useful for mapping and validation, and data logging and recording, for reports.

Three types of sensor technologies are Resistive, Capacitive, and Thermal Conductivity sensing. Resistive sensors are useful when using them in remote locations. Capacitive sensors are beneficial for wide RH range and condensation tolerance. Thermal conductivity sensors are beneficial in corrosive environments that have high temperatures. The type of sensor used will depend on the type of environment. Commercial and office buildings often have humidity sensors in their HVAC systems, which assists in keeping the air safe and healthy to breathe. Humidity sensors also have industrial uses for the manufacturing of materials that are sensitive to moisture. As well, humidity sensors are used for collecting data for weather stations and ocean research where humidity has to be measured and recorded for a period of time to evaluate patterns and forecast weather.

Advancements in technology have made it possible to control humidity for a variety of reasons such as to maintain healthy indoor air, protect items from moisture exposure, and for different research applications. There are a number of companies online that specialize in providing quality hygrometer that are highly accurate and resistant to damage from physical and chemical contaminants.

The Importance of Humidity Inside of Your House


Humidity is the concentration of water in the air. This is very important to consider even when inside the home. You should monitor the levels of humidity in your home to keep them from getting too high or too low. Now that many people spend more and more of their time indoors, it is important that the conditions indoors are healthy.

What are the risks? If you would like to avoid mold/mildew, fungi, viruses, dust mites, harmful bacteria, termites and carpet ants, then you should monitor the level of humidity in you home. All of these things breed in moist, humid conditions. A runny nose, itchy eyes, increased chemical sensitivity, throat irritation and headaches can result from the development of these things because of high humidity and dampness, or low humidity and dryness inside of a home. High humidity in the home can make it more difficult to breath, which can cause fatigue. Low humidity is bad for your eyes and skin.

If you have wooden structures in your home, they can be damaged by expanding or contracting with the changes in moister in the surrounding air. Furniture can crack, weaken and develop mildew if not kept at the right humidity. When this happens, a poor smell can develop if not taken care of. You don't really want small green organisms taking over in your living room, do you?

If you have high levels of humidity in your home, you might want to consider purchasing a dehumidifier to reduce the dampness of the air. Higher levels of humidity are likely in the summer months. You should plan to buy a humidity sensor to find out and keep track of what the humidity level in your home is. An air conditioner may assist you in balancing the humidity in the air during the summer. Lower levels of humidity are likely in the winter. Since this can also affect your health and cause dry skin and throat irritation, you should consider using a humidifier to raise the humidity to a healthy level.

Whether you live in an apartment or a house, you should get a humidity sensor, an air conditioner and humidifier. To keep you and your family comfortable and healthy, you should take the proper precautions to insure that the humidity levels are not extremely high and not extremely low. This will also protect your furniture. This is just a word to the wise, since you will probably spend most of your time indoors, if you are like most people nowadays.

Predict The Future With A Humidity Temperature Sensor


A humidity temperature sensor is a handy equipment to have. If you know how to read the data that it provides, you can use it to essentially control your indoor environmental conditions. Most people think that just controlling the temperature of a room or office is the key to feeling at optimal levels. While this is partially true, you also need to consider the amount of water vapor in the air or the "humidity" in the equation.

There are many definitions of a comfortable indoor environment. It may mean different things to different people. It could mean that a home or desk at work adorned with so many beautiful things like precious ornaments, valuable artifacts and expensive decorations.

For some individuals, they look at the practical side before they consider their haven comfortable and convenient. And one of these factors is the ability of the space to control and regulate the temperature, thereby making it livable and conducive to more efficient working conditions in extreme hot summer days or cold freezing nights.

An efficient home is an insulated home, capable of defending itself from scorching heat conditions. High humidity inside your precious abode is a sure killer of your family and your health. Yes, we are speaking of mold and mildew growth.

In addition, they will certainly shorten the lives of your expensive appliances and electronics which do not thrive in extreme heat condition. The microchips embedded in your laptop, computer and other gadgets easily break apart in terms of function when exposed in heat.

Thus, there is an important need, in such conditions, to have your space insulated to prevent trapping heat inside it. As you may guess, in order for the occupants to be comfy and television and computers to function properly it could get costly if you do not have a way of monitoring your indoor conditions and nip potential issues in the bud.

By having a humidity temperature sensor on hand, it can alert you to potential issues before they happen. It could even allow you to allocated funds in advance to purchase new air conditioning systems because you can practically foresee that replacement of the old system may be in the cards.

It is highly important that you have sufficient knowledge on cooling systems. Be friends with your heating, ventilation and cooling systems. Treat them right with regular maintenance and repairs if necessary and they will, in turn provide you with efficient indoor environments.

Humidity Measurement


The measurement of pressure dew point in compressed air systems or gas distribution networks has become more important recently. Manufacturers worldwide are getting aware of negative effects of having too much moisture in the air / gas pipes, as it can cause:


Corrosion in the pipes
Reduces lifespan of pneumatic parts
Failures in actuators
Contamination of compressed air system in general
Unscheduled production stops.
Incalculable additional production costs

Dryers used to remove moisture from gas, are not always performing as they intend to do, mostly caused by a poor maintenance. Humidity measurement acts as a kind of insurance system, monitoring the dryer performance and indicating alarms whenever values are out of valid ranges. As a result it provides:


Fast responses to failures in compressed air drying through permanent monitoring of pressure dew point.
Increase the lifespan of compressed air system and it components.
Make maintenance of the compressed air system more efficient.
Ensures stable quality of products through less problems in operation of the system

But humidity measurement is not only restricted to applications in air / gas drying. There are many more processes in industry where a well monitored dew point is crucial for the overall process and the quality of the products.

Applications for dew point monitoring:


Plastic injection and blow molding
High voltage switch gears and transformers
Spray painting process
Bottle filling
Medical gases
Pipeline drying

Compressed air is used in brake systems and door openers of rail vehicles. It has to be free of any condensate otherwise the brake system and the pneumatic door openers may freeze in winter and corrosion damages in the distribution network and at pneumatic components (cylinders, valves) can occur. For this reason a regular dew point measurement is essential.

The humidity sensor provides reliable and long term stable dew point monitoring in industrial applications. The newly developed sensor features improved signal and stability in demanding industrial applications. Drifts caused by temperature changes, dust and aging are eliminated by the electronics providing reliable measurements. Recalibration interval thus could be increased to 2 years.

The measured dew point is output via a 4-20 mA signal output. The integrated display shows online measurement values and alarm status. One alarm can be programmed which will activate a relay.

Benefits


Humidity sensor for low dew point applications down to -80 oC
Graphic display, relay output
IP65 casing provides robust protection in rough environment
Very fast response time ensures safe and reliable indication
Can be installed directly into dryers through G 1/2" thread
High accuracy of ±2 oC dew point
