What is Thermocouple?

Thermocouple is the most commonly used temperature measuring device in temperature measurement. Thermocouple is characterized by wide temperature measuring range, stable performance and sufficient measurement accuracy, which can meet the needs of temperature measurement in industrial process.Simple structure, good dynamic response;The output is an electrical signal, which can be transmitted far, facilitating centralized detection and automatic control.

The principle of thermocouple temperature measurement is based on thermoelectric effect.When two different conductors or semiconductors are connected into a closed circuit, when the temperature at the two contacts is different, the circuit will generate a thermoelectric potential, which is called the thermoelectric effect, also known as the sebeik effect.
