When there is a temperature difference between the two attachment points 1 and 2 of conductor A and B, the two The phenomenon of generating electromotive force and forming a current in the loop is called the thermoelectric effect. Thermocouples use this effect to work._x000D_ _x000D_ Application: Thermocouples are widely used in various enterprises and institutions such as petroleum, water conservancy, chemical industry, metallurgy, electric power, environmental protection, etc., to achieve temperature measurement and direct contact with the measured object.
