Temperature sensors are utilized to measure temperature changes in the environment. They can be used in a variety of applications and their own working principles are dependent on the type of temperature sensor being utilized. One type of temperature sensor, the thermostat, works by mechanically measuring changes in temperature.

Thermostats are mechanical temperature sensors that are activated when the temperature of an environment, or the ambient temperature, rises or falls below a set threshold. These devices are triggered by a wax pellet placed inside the thermostat that expands when heated and contracts when cooled. As the wax pellet expands and contracts, a spring is also activated that then in turn triggers a switch to open or close when the set point is reached.

The beauty of thermostats lies in their simplicity. They are designed to be robust and reliable, and they can easily be pre-programmed by changing the levels of the wax and spring. This means that they can be used in scenarios where a digital temperature sensor cannot, as they do not require any power source and can be used in remote locations. Additionally, thermostats only activate when the temperature of their environment reaches a preset level, meaning they do not need to be monitored or reset continuously.

Thermostats can be used to control and regulate a variety of systems. These systems can range from cars to mechanical cooling systems, HVAC systems, or even industrial safety systems where temperatures must be monitored. They are also widely used in household appliances such as refrigerators, air conditioners and ovens.

In addition to controlling systems, thermostats can also be used to monitor temperature irregularities, as well as to turn on and shut off systems as necessary. This is useful in scenarios such as assembling computer chips where the room temperature must adhere to certain regulations.

Thermostats are an important and widely used type of mechanical temperature sensor. From controlling systems to monitoring temperatures, they are one of the most reliable and dependable temperature sensors available. Their robust design allows them to be used in a variety of environments, and they can be easily pre-programmed for whatever situation they are needed for.
