Application Field and Working Principle

315300090020 thermoelectric module thermostats are the most commonly application in automatic temperature control systems. The thermostat is composed of a thermocouple device and a temperature switch. Its appearance is a small box containing a disc or cylinder in the center, with two metal spherical heads protruding from the top and bottom of the box.

The two spherical metal heads on the top and bottom of the detector are called "active" and "floating" respectively. "Active" and "floating" are the two sensing parts of the temperature switch body. The two are composed of two different metal materials, and the two sensing elements of the thermocouple device contained in the detector are connected respectively. With the change of temperature, due to the change of the resistance ratio of the two metals, the power generated by the temperature switch changes, so that it can actively respond to the change of the temperature.

The thermostat can be applied to temperature control or over temperature protection of refrigerator, water heater, air conditioner, fryer, timer, home appliance motor, and other products. Its detection principle is based on the thermal property of metal materials. The temperature switch is composed of two different metal materials, which are used as two different working elements, generally called "active" and "floating". They are fixed to the bottom of the shell and respectively connected to two pins of a switch inside. When the temperature changes, the relative resistance change of the two metal materials changes, thus causing the switch in the box to turn on or off.

The thermostat is a low output temperature switch, which utilizes the thermoelectric effect and temperature coefficient characteristics of different conductors. The thermoelectric effect is the ability of certain materials to generate electrical signals when exposed to extreme temperatures. As the temperature rises and the resistance ratio of the two elements changes, the voltage difference between them is also affected, causing the contact point of the switch to close and form an electric circuit.

The 315300090020 module thermostat is very versatile and can be used in a wide variety of applications. Because the unit works on an electrical temperature switch principle, it is unaffected by vibration and can be used for a variety of temperature control applications. It can not only ensure the accuracy of data collection, but also can use in the sensing temperature of precise operation. And because of its simple structure and installation, it is especially suitable for testing and controlling the temperature of automatic equipment.
