WR series of prefabricated thermocouple, WR series industrial thermocouple as the temperature measurement sensor, usually with temperature transmitter, controller and digital display table, such as process control system, to directly measure or control in the production of a variety of 0 Fluid over a range of 1800 ℃, steam and gas medium and solid surface temperature. Thermocouple is composed of two different components of the conductor when two ends synthesis loop, when the two junction temperature is not at the same time, will produce thermal current in the circuit. If the working end of the thermocouple and the reference side there is temperature difference, the digital display table will show the thermocouple thermoelectric potential of the corresponding temperature value. Electric hot thermocouple will grows with the temperature measuring end, it is only with the size of the thermocouple temperature at the ends of the materials and relevant, has nothing to do with the hot electrode length and diameter. The appearance of all kinds of thermocouple is often due to the need to vary, but they are roughly the same basic structure, usually by the hot electrode, insulation sleeve to protect the main components such as pipe and connection box.
