Thermocouple is a commonly used temperature measuring element in temperature measuring instruments. When two ends of a conductor with two different components are connected to a combined circuit, when the thermocouple temperatures at the two junctions are different, a thermal current will be generated in the circuit.
If there is a temperature difference between the working end and the reference end of the thermocouple, the display meter will indicate the temperature value corresponding to the thermoelectric potential generated by the thermocouple. The thermoelectric heat of a thermocouple will increase as the temperature of the measuring end rises. Its size is only related to the thermocouple material and the temperature at both ends, and has nothing to do with the length or diameter of the thermal electrode.
The appearance of various thermocouples is often very different due to their needs, but their basic structure is roughly the same. They are usually composed of main parts such as thermal electrodes, insulation protection tubes and junction boxes. They are usually associated with display instruments, recording instruments and electronic adjustment Supporting device.
