Product Description
K Type Extension Thermocouple wire with Stainless Steel Shield Wire
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.
