Temperature Sensors: Thermostats - Mechanical

Temperature Sensors are devices which measure temperature and alert when it rises or falls beyond specified limits. Thermostats are mechanical temperature-sensing devices used to trigger an action when temperature exceeds a pre-determined limit. This is normally done by using a bimetallic strip, a switching bellows, a bellows switch or an electrical switch. The most commonly used device is the bimetallic strip.

Application Field

Thermostats are mainly used in home and industrial settings for temperature control and regulation. Homeowners typically use them to regulate temperature in their homes, and as thermostats are often inexpensive, they are widely used in the commercial and industrial context to keep the environment and products stable and consistent. Automobile engines also feature thermostats to ensure control of the engine\'s heating and cooling systems.

Working Principle

The primary purpose of a thermostat is to sense temperature and to trigger a change in the environment when it is exceeded. The principle of the working of a thermostat is based on changes in temperature that cause changes in the shape or size of a temperature-sensitive element such as a bimetallic strip, bellows-style switch, electrical switch, etc. Such an element is referred to as a bi-metallic strip.

When the temperature varies, the shape or size of the bi-metallic strip also varies and affects a mechanical linkage or an electrical switch. The linkage or switch is then used to trigger the desired action. For instance, when the temperature increases, the deformity caused by the rise in temperature will cause the strip to contract, thus forcing the electrical switch to be switched on. Similarly, if the temperature falls and the strip expands, the switch will be turned off.

The working of such a thermostat is simple and reliable. This is why they are often used in various applications to maintain a constant temperature. They also offer great accuracy and reliability.

Conclusion

The 3150 00770036 is a mechanical thermostat that can be used for temperature control and regulation in both home and industrial settings. The device is based on the principle of a bi-metallic strip, which expands or contracts when the temperature changes, and causes a mechanical or electrical switch to be activated when the pre-determined temperature point is exceeded. The device offers excellent reliability and accuracy and is thus very useful in various applications.
