Temperature Sensors - Thermostats - Mechanical

Mechanical temperature sensors are an integral component in many applications. They measure temperature and then regulate the airflow as the temperature rises and falls. The simplest form of a mechanical temperature sensor is a thermostat. A thermostat works by detecting changes in temperature and then triggering an electrical switch, such as a fan, to turn on or off as needed.

The most common type of mechanical temperature sensors are the bi-metallic type. The bi-metallic type utilizes two strips of metal, one with a higher coefficient of thermal expansion and one with a lower coefficient of thermal expansion. When the temperature changes, the two metals expand at different rates, causing the strip to bend. This movement is used to activate a switch.

Another type of mechanical temperature sensor is the bulb and capillary type. This type of sensor consists of a bulb filled with a liquid, such as mercury, and a capillary tube. The tube is wrapped around the bulb and is connected to a movable plate or diaphragm. As the temperature changes, the liquid in the bulb will expand or contract, causing the plate to move. This movement is then converted into an electrical signal, usually in the form of an electrical switch.

The third type of mechanical temperature sensor is a bimetal strip. This type of sensor utilizes a special strip of metal that is made up of two different metals bonded together. When the temperature changes, the metals expand or contract at different rates, causing the strip to bend. The movement of the strip is used to activate switches.

Finally, the fourth type of mechanical temperature sensor is a thermistor. A thermistor is a temperature sensitive resistor that uses a combination of resistance and temperature to produce a voltage. As the temperature increases, the resistance decreases and the voltage increases. This voltage can then be used to activate switches.

The 345000210605 application field is the use of mechanical temperature sensors in a variety of applications, such as automotive, industrial, medical, gaming, and more. They are commonly used in computers, HVAC systems, refrigerators, and other temperature-sensitive applications, where accurate temperature readings and control are important. The working principle of a mechanical temperature sensor is dependent on the type of sensor, but they all rely on changes in temperature causing a physical reaction that is then converted into an electrical signal.

Mechanical temperature sensors are an important part of many modern applications and can provide an accurate and reliable means of detecting and controlling temperature levels. As technology advances, there will likely be newer and more sophisticated mechanical temperature sensors developed that can be used in even more applications.
