Thermocouple compensating wire
Thermocouple compensating 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°C. 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).
