2、 Working principle Operational principle

The working principle of a thermocouple is that two conductors with different compositions are welded at both ends and form a circuit. The temperature measuring end is called the measuring end, and the wiring terminal end is called the reference end. When there is a temperature difference between the measuring end and the reference end, a thermal current will be generated in the circuit. When connected to a display instrument, the instrument will indicate the corresponding temperature value of the thermoelectric potential generated by the thermocouple.

Thermocouple Working principle. Twodifferent components of the conductor ends by welding, form loop, Directtemperature measuring end called the measuring end, The terminal end is calledthe reference terminal. When the measuring end and the reference end Temperaturedifference, Will be in the loop Thermal current, Connected to displayinstrument, The instrument will indicate the thermocouple Thermal electromotiveforce Corresponding temperature.

The thermoelectric potential of a thermocouple will increase as the temperature at the measuring end rises. The magnitude of the thermoelectric potential is only related to the material of the thermocouple conductor and the temperature difference between the two ends, and is independent of the length and diameter of the thermoelectric electrode.

Thermocouple electromotive force withThe measuring end temperature and growth, The size of thermal emf Only andthermocouple conductor material And the temperature difference between the twoends of the relevant, And the power electrode length, diameter.

Prefabricated thermocouples are mainly composed of a junction box, protective tube, insulating sleeve, terminal block, and thermoelectric electrode, and are equipped with various installation and fixing devices (see the figure below)
