What is a thermocouple?
Thermocouple is a temperature measuring element commonly used in temperature measuring instruments. It directly measures the temperature, converts the temperature signal into a thermoelectromotive force signal, and converts it into the temperature of the measured medium through an electrical instrument (secondary instrument). The shape of various thermocouples is often very different due to needs, but their main characteristics are roughly the same.
Main features:
1. Simple assembly and easy replacement;
2. Compression spring type temperature sensing element, good shock resistance;
3. High measurement accuracy;
4. Large measuring range;
5. Fast thermal response time;
6. High mechanical strength and good pressure resistance;
7. High temperature resistance;
8. Long service life.
The thermocouple developed by our company is often used in the gas hypoxia protection device. The principle is that the burning of the constant flame causes the thermocouple to generate thermoelectric potential, and the electromagnetic valve is opened to make the gas appliance work normally. When the gas appliance fails to work normally or the constant flame is extinguished, the thermocouple cannot generate thermoelectric potential. At this time, the solenoid valve cuts off the gas source through the spring reset to ensure the safety of life.
