For S Or R Thermocouple Compensating And Extension Wire Type SC Or SR
For S Or R Thermocouple Compensating And Extension Wire Type SC Or SR
Thermocouple compenstaing wire is used to connect the electrode ( cold side of thermocouple ) with display instrument in order to form a temperature measurement system. The working temperature is -25~200 ℃. Our plant mainly manufacture type KX,NX,EX,JX,NC,TX,SC/RC,KCA,KCB, and WREC compensating wire for thermocouple,and they are used in temperature measurement instruments and cables. Our thermocouple compensating products are all made abiding by GB/T 4990-2010‘Alloy wires of extension and compensating cables for thermocouples’( Chinese National Standard) ,and also IEC584-3‘Thermocouple part 3-compensating wire‘(International standard).
