The thermocouple is combined by two different alloy materials. Different alloy materials produce different thermal potentials under the action of temperature, and the thermocouple is produced by different thermophototives produced by different alloy materials at temperatures. The two ends of the conductors of two different ingredients are engaged as looping. When the temperature of the joint point does not, the electric potential is generated in the loop, which is called the thermoelectric effect, and this electromotive force is referred to as a thermoelectric force. The thermocouple uses this principle to perform temperature measurement, where directly used as one end of the measuring medium temperature is called the working end, and the other end is called the cold end; the cold end is connected to the display instrument or a supporting instrument, and the display instrument will indicate that the thermocouple is generated. Thermal potential.
