Product Description

 

Fe-CuNi thermocouple (type J) is also named Fe- Constantan thermocouple. The positive leg Fe(JP) is
made by pure Iron, and the main chemical composition of negative leg Constantan (JN) is Cu: Ni≈55%;
45%. Although they are all called Constantan, JN does not give the same EMF output curve as EN and TN,
it cannot be instead by other Constantan.
The operating temperature range of type J thermocouple is -210~1200ºC, but it is usually used in the
temperature range 0~750ºCc due to embrittlement of Iron.
Type J thermocouple has good resistance to oxidation and high EMF output against Platinum 67, with
good temperature accuracy, sensitivity and stability. It is recommended for vacuum, oxidizing, reducing
or inert atmospheres, but it can not be used in sulphurous atmosphere above 500ºC.

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
-25~200ºC. 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).
