Temperature sensors, such as thermostats, are mechanical devices that measure and control temperatures in areas as diverse as industrial ovens to the treatment of wastewater. This article will discuss the application field and working principle of such temperature sensors.

Application Field

Temperature sensors, such as thermostats, are used in a variety of industries to monitor and control temperature levels. They are used in many industrial applications, such as in furnaces, furnaces, dryers, kilns, boilers, and in the food processing industry. Additionally, they are also used in medical and laboratory applications, such as incubators, Chromatography equipment, infrared inspection systems, sanitation equipment, and sterilization equipment.

Temperature sensors are also used in automotive applications, such as air bag control, air conditioning systems, climate control, engine cooling systems, and oil and fuel temperature monitoring. Additionally, temperature sensors are employed in the transportation industry, such as within aircraft, ships, trains and motor vehicles. They are also used in agricultural applications, such as in barns, silos, grain storage, and greenhouses.

Working Principle

The working principle behind temperature sensors is relatively simple. Such sensors typically contain an internal thermistor that acts as a transducer, converting changes in temperature into an electrical signal. This signal is then sent to an external device, such as a controller or indicator, that will then trigger an appropriate action based on the temperature reading. For example, a controller could be programmed to start the cooling process if the temperature reading reaches a certain level.

These temperature sensors operate in a variety of temperature ranges, from sub-zero temperatures, such as for cryogenics, to high temperatures, such as for coal-fired power plants. Additionally, many temperature sensors are designed to measure temperature in a wide range of fields, such as in laboratories, manufacturing plants, and research centers.

Temperature sensors are useful in a variety of industrial and consumer applications, from medical and laboratory use to air-conditioning systems and automotive use. Knowing how to effectively use and maintain such sensors is essential in order to ensure safety and accuracy.
