Functions And Applications Of Data Logger

Data Logger, which is also known as a Data Recorder, is an electrical device that performs the task of recording data over a time period. It can even record data from sensors or instruments which are externally located. Data logger consists of inbuilt sensors that have the capacity to read data from external sensors. It works on microprocessor and battery charger, the size of this device is small. You can attach this device with a computer and retrieve data. The device can also act as a standalone instrument, as it can work with its own keyboard and display screen.

Data logger basically captures as well as stores data, this device has got data capturing elements like plug-in-board. It also has a special inbuilt device which is the data acquisition device that is like a serial communication system which works from the main computer. It is the main computer which performs the function of data recording system in real time.

Now let us check out some of the basic functions of data loggers. They have a multi functional ability. Let it be any sort of electrical signals, it has got the capacity to read all of these signals in a very minimum time frame.

Once the data recorder reads all types of electrical signal, it stores them straight in the internal memory. And once the internal memory captures this data, you can easily download this information straight to your computer. But this does not mean that loggers always need the help of a computer, as it can work without a computer too.

Nowadays people use data recorders for a variety of reasons. Now let us take a sneak peek at some of the basic applications of data recorders. They are used in the weather station in order to record data like wind speed, temperature, solar radiation etc. It is also used in test equipments to record hydrographic data like collecting information related to water depth or level.

The logger is also used to record data like moisture level of soil, gas pressure, tank level, road traffic, vehicle test, monitoring environmental issues, application for troubleshooting, railway signal, calibration service, management of energy consumption, research in wildlife and many more.

In many industries where the basic function is to store food items, you will find a massive use of data recorders. Here the device not only reads the temperature but it has humidity sensor which reads the humidity and makes sure that goods are in their perfect condition. Even in many restaurants also people use this device in the refrigerator in order to detect the temperature. It provides information of the temperature and makes sure that the food is in its best condition.

Data loggers come in both small as well as large sizes. Moreover, you will find this device in various price ranges, so depending upon your usage and budget you can choose your data logger. If you are looking for cheap data loggers then you can opt for the single channel loggers, but if budget is not a constraint for you then you can opt for the multitude data loggers.

Data Logger A First Step To Quality Control

There are both negative and positive connotations in regards to the term data logger. Many seem to believe a logger is a bad thing. As if people are trying to spy on you, or get to your information. In a way a logger does get to your information, but most are used for good purposes.

When you get down to it a logger is a tool. Much like typing onto a screen, it is logging your data in a way. Many high tech pieces of equipment use loggers. The output is captured in data bases for further work, but this data is quite important. Certain multi million dollar pieces of equipment can be kept running with less expense by monitoring the output of these loggers.

Most major equipment, from air conditioning systems in large buildings, to heavy equipment, to manufacturing equipment have a variety of sensor throughout the machinery. It could be as simple as monitoring the power supply for a large computer. Sensor help to read even tens of thousands of a fluctuation in power, or tolerances. With these readings, replacement parts can be ordered ahead of time, and while normal maintenance happens, the parts get installed saving time and money on a production line.

In some higher calibrated equipment humidity is a major concern. It can easily affect efficiency and wear of an item. Humidity sensors play a vital role in adjustment and life of this kind of equipment, and can signal support personnel for deeper service when certain conditions are met.

When it comes down to a special drill press for circuit boards, or any fine tuned equipment, calibration service is very important. On some circuit boards for a computer, tolerances of less than a human hair are needed to the parts that get attached are precise and work right the first time. Calibration of a drill, or a robot to place those parts is beyond important.

It is quite frustrating to get a new cell phone, or some new electronics and have issues. Quality control should catch those issues prior them happening. Specialized test equipment helps in that role. Whether it be robotic or human operated, test equipment could be a simple fixture that powers up a monitor, a phone, or other product for special testing, or even down to individual components to ensure that a switch works within tolerances.

A data capture scheme can be a simple software or hardware device. This is where it can become negative also. Some loggers are never seen, you simply have no idea that information is being captured at all. Your company can use these, especially with sensitive info, or top secret clearances. It is rare to see some of this as the costs to monitor, and put the data to use is not a simple thing to do.

Overall these devices and programs are very important for the manufacturing world. The negative spying connotations aside, we use them every day. Even your voice mail is a logger of sorts, and we even delve deeper into the info to bring out meaning. The same thing happens in all types of equipment, even your car. That car's computer is a data logger, and helps keep everything running smooth.
