Frequently Asked Questions
Fulu's "class" begins
thermocouple
When two different conductors or semiconductors A and B form a circuit, and their two ends are connected to each other, as long as the temperature at the two nodes is different, with one end having a temperature of T, it is called the working end or hot end, and the other end having a temperature of T0, it is called the free end (also known as the reference end) or cold end, an electromotive force will be generated in the circuit, and the direction and magnitude of this electromotive force are related to the material of the conductor and the temperature of the two nodes. This phenomenon is called the "thermoelectric effect", and the circuit composed of two conductors is called a "thermocouple". These two conductors are called "thermoelectric poles", and the generated electromotive force is called the "thermoelectric potential".
This relationship has been widely used in practical temperature measurement. Because the cold end t0 is constant, the thermoelectric potential generated by the thermocouple only changes with the temperature of the hot end (measuring end), that is, a certain thermoelectric potential corresponds to a certain temperature. We can achieve temperature measurement by measuring thermoelectric potential, which is the principle of thermocouple.
