HUONA produces different types of compensated cable for thermocouple, such as KX type, NX, EX, JX, NC, TX, SC / RC, KCA, KCB. We also produce all cables with insulation such as PVC, PTFE, Silicone and fiberglass.
The compensated cable is mainly used in thermal measurement instrumentation. If the temperature changes, the cable responds with a small voltage that passes to the thermocouple it is connected to and we already have the measurement.
The thermocouple compensation cables can also be termed as instrumentation cables, since they are used for process temperature measurement. The construction is similar to pair instrumentation cable but the conductor material is different. Thermocouples are used in processes to sense temperature and is connected to the pyrometers for indication and control. The thermocouple and pyrometer are electrically conducted by thermocouple extension cables / thermocouple compensating cables. The conductors used for these thermocouple cables are required to have similar thermo-electric (emf) properties as that of the thermocouple used for sensing the temperature.
Our plant mainly manufacture type KX,NX,EX,JX,NC,TX,SC/RC,KCA,KCB 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).
The representing of the comp. wire: thermocouple code+C/X , e.g. SC, KX
X: Short for extension, means that the compensation wire's alloy is as the same as the the alloy of the thermocouple
C: Short for compensation, means that the compensation wire's alloy has similar characters with the thermocouple's alloy in a certain temperature range.
