Temperature sensors and thermostats are devices used to detect temperature changes and regulate temperature levels. In terms of mechanical applications, these devices are used to regulate temperatures in industrial processes and equipment. In this article, we will discuss the application fields and working principle of temperature sensors and thermostats.

1. Application Field of Temperature Sensors and Thermostats

Temperature sensors and thermostats can be used in a variety of applications. These devices can be used to measure temperature in industrial processes and equipment, such as boilers, heat exchangers, and furnaces. They can also be used to monitor the temperature of a variety of liquids and gases, such as oil, water, and air.

Temperature sensors and thermostats can also be used to regulate temperature levels in industrial processes. For example, if the temperature of a liquid rises above a certain level, a temperature sensor can be used to trigger an alarm or shut off the process to avoid damaging the equipment and product. Additionally, thermostats can be used to regulate the temperature of a system by maintaining a specific level of temperature.

2. Working Principles of Temperature Sensors and Thermostats

The working principles of temperature sensors and thermostats are quite simple. Temperature sensors work by measuring changes in temperature and converting these changes into electrical signals which can be read by devices such as a computer or a display. Generally, temperature sensors use two different types of sensing elements: thermocouples and resistance temperature detectors (RTDs).

Thermostats, on the other hand, use a combination of mechanical and electrical components to regulate temperature levels. Generally, these devices use a metal bimetallic strip that bends with changes in temperature. As the bimetallic strip bends, it transfers motion to a switch that either turns on or off an electronic device, such as a heating or cooling element. Additionally, some thermostats also include a temperature sensor to provide feedback to an electronic or mechanical device to help regulate temperature levels.

Conclusion

To conclude, temperature sensors and thermostats play an important role in the industrial world. These devices are used to detect changes in temperature and regulate temperature levels in industrial processes and equipment. Temperature sensors work by converting changes in temperature into electrical signals while thermostats rely on a combination of mechanical and electrical components to regulate temperature levels.
