Temperature Transmitter 
 WR series of industrial thermocouple as a temperature measurement sensor, usually associated with temperature transmitters, regulators, and display instruments, such as supporting the use of the composition of the process control system for the direct measurement or control of the various production processes within the range of 0-1800 ℃ fluids, steam and gases, and solid surface temperature. 
 Thermocouple is connected by the conductor at both ends of the two different components of the synthesis loop, when the two junction temperature does not, it will in the loop thermal current. If the end of the thermocouple and reference junction temperature difference, the display meter will be instructions corresponding to the thermoelectric power generated by the thermocouple temperature. 
 Thermocouple thermal electric heat will measure the junction temperature rise and growth, its size is only with the temperature of the thermocouple material and at both ends, and the length of the hot electrode, the diameter has nothing to do. 
 The shape of various thermocouple is often needed, which is very different, but their basic structure is substantially the same, usually by the hot electrode, the insulating sleeve of the main component of the protective tube and the junction box.
