Humidity Analyzers And Temperature Sensors Explained


Humidity analyzers, also popularly referred to as moisture sensors or hygrometers, together with temperature sensors are technical gadgets that not only play an important role in various and diverse manufacturing and industrial processes but also are incorporated in many ordinary home appliances we probably have at home.

Humidity Sensors

In industrial and manufacturing environments, moisture sensors are highly sophisticated technical gadgets that enable factory operators as well as industry managers make sure that the product being produced is being manufactured within acceptable levels of humidity. Industries need to comply with high industry quality standards and hygrometers help them in this task. From the human and pet food industry to chemical and pharmaceutical labs, to the wood and leather industry, these devices have multiple uses. For instance, they are useful to determine if the potato chips are packed crispy, if the breakfast cereal will be crunchy and tasty when we eat it every morning and that the chemical compounds used to prepare a certain medicine have not lost their healing properties as result of being exposed to a too dry or wet environment.

In industrial environments there isd usually more than one moisture analyzer set up to monitor the humidity content of the product being manufactured as the acceptable range may vary from step to step of the manufacturing process. In order to make sure that the product complies with the quality standards, a sample is taken and weighed. Then it is introduced in the moisture analyzer and dried. Once dried it is weighed again. The difference between the two weights tell the operator if the environment is dry enough or if further changes need to be made.

As regards home appliances, the air conditioner has a moisture sensor that helps the device know when the air conditioned room has reached the desire level of dryness. Whenever it starts getting humid again, the hygrometer automatically triggers the air conditioner again. Many clothes dryers also come with hygrometers and they help women make sure that their clothes are dried efficiently without being over exposed to dryness.

Antique shops also have moisture analyzers as they are useful to protect relics and antiques from the devastating effect of humidity.

Temperature Sensors Temperature sensors are also more popularly known as thermometers. In clothes dryers they are very helpful as they can be used to make sure that the delicate clothes fibers are not exposed to overheat unnecessarily.
