In the circuit, the bimetal temperature controller is an important component, which can control the working state of the circuit according to the change of temperature. So, what is the working principle of the bimetal temperature controller? Let’s take a look at it.
The basic structure of bimetallic sheet temperature controller Bimetallic sheet temperature controller is mainly composed of thermocouple, connecting wire, metal sheet, insulation layer, protective sleeve, etc. Among them, the thermocouple is a temperature measuring element, which can convert the temperature change into an electrical signal; The metal sheet is a kind of temperature sensing element, which can be deformed as the temperature changes.
When the circuit is energized, the thermocouple generates an electrical signal, which changes with the temperature. When the temperature rises, the metal sheet will be heated and expanded, so as to contact the connection line of the thermocouple, forming a closed loop; When the temperature drops, the metal sheet will shrink, disconnect from the connection line, and the circuit is disconnected. In this way, the on-off control of the circuit can be achieved through the expansion and contraction of the metal sheet.
Bimetal thermostat is widely used in various electrical equipment, such as refrigerators, air conditioners, water heaters and so on. In these electrical equipment, the bimetal temperature controller can control the start and stop of the compressor, so as to achieve temperature control.
In short, the bimetallic sheet temperature controller is an important component, which can realize the on-off control of the circuit through the combination of thermocouple and metal sheet, so as to achieve the control of temperature.
