Prefabricated thermocouple details

Overview of WR series industrial thermocouples as temperature measurement sensors, usually used in combination with temperature transmitters, regulators, and displays to form process control systems, directly measuring or controlling the temperature of fluids, steam, gas media, and solid surfaces within the range of 0-1800 ℃ in various production processes. When a thermocouple connects two conductors of different compositions to a circuit, if the temperatures at the two connection points are different, a thermal current is generated inside the circuit. When there is a temperature difference between the working end and the reference end of the thermocouple, the temperature value corresponding to the thermoelectric potential generated by the thermocouple will be displayed on the monitor. The thermoelectric heat of a thermocouple increases with the temperature at the measuring end, and its size is only related to the material of the thermocouple and the temperature at both ends, regardless of the length and diameter of the thermoelectric electrode. The appearance of various thermocouples varies greatly according to needs, but the basic structure is basically the same, usually consisting of the main components such as the hot electrode, insulation cover protective tube, terminal box, etc.
