Temperature Sensors - Thermostats - Mechanical

Thermostats are surprisingly complex pieces of equipment. They are used in a wide variety of applications to maintain a constant temperature. A mechanical thermostat is a type of temperature sensor that uses mechanical elements and can be either an analog or digital device.

Analog Mechanical Thermostats

Analog mechanical thermostats use a traditional, mechanical system to control and monitor temperature. They typically contain a bi-metallic strip which have two metals bonded together. This strip will respond to temperature changes and bend in response to the new temperature. By attaching the strip to a control circuit and a device that needs temperature control, the thermostat can open and close a circuit to the device to adjust the temperature.

Digital Mechanical Thermostats

Digital mechanical thermostats are a more advanced form of temperature control. They can be programmed to dial in specific temperature settings, and can also use timers to initiate temperature changes at preset intervals. A digital mechanical thermostat\'s main components consist of a mechanical device such as a bimetallic strip, a control circuit to drive the strip, and a processor to interpret the data from the strip. A digital mechanical thermostat is ideal for thermostatic applications where accuracy and control are important.

Advantages and Disadvantages of Mechanical Thermostats

The advantages of mechanical thermostats include their affordability and reliability. They are relatively inexpensive to purchase and are designed for long periods of continuous use. In addition, analog mechanical thermostats do not rely on batteries which makes them convenient to use. The disadvantage of a mechanical thermostat is that it is not as accurate as a digital model and does not provide the same level of control.

Applications

Mechanical thermostats are used in a wide range of applications. They are found in both domestic and commercial uses, typically watching over heating and cooling systems and other temperature-sensitive mechanisms. They are also commonly found in industrial applications such as chemical processing and refrigeration systems, as well as medical and dental equipment.

Conclusion

Mechanical thermostats are a cost-effective and reliable temperature control solution. They are widely used across many industries and are able to both maintain and monitor temperature. Analog thermostats are cheaper and do not rely on batteries, while digital thermostats are more accurate and offer more control.
