KX / EX Compensating Wire and Cable Thermocouple Extension Cable
Compensating Wire And Cable For Thermocouple
Product standard: GB/T4989-94
Applications
The compensation wire or compensation cable is one pair or multi-pair insulation layer wire or cable that possesses same electromotive force of matched thermocouple within the scope of certain temperature. Use them to connect thermocouple and measuring device in order to compensate the error produced by temperature change at the joint place of thermocouple. The compensation wire or compensation cable can be divided into two kinds, I. E. Extended type and compensation type.
Length and wrap
The total length of cable is not less than 100m, Shortage length more than 20m may be delivered, but not exceed 10% of the total length delivered special requirement to be discussed between the supplier and the buyer.
| characteristics | advantage | |
| Compensation tape KX,EX,JX,TX,NX |
The normal chemical component and thermal electromotive force value of alloy wire all the same from the matched thermocouple | Can guarantee high precision within wide scope of temperature Choose suitable insulation material, may expand the scope of temperature |
| Extended type BC,RC,SC,KC,NC |
The normal chemical component and thermal electromotive force value of alloy wire is different from the matched thermocouple. But its thermal electromotive force is same as the thermal electromotive force value of matched thermocouple at 0ºC~100or 0~200ºC | Cheap in price Choose suitable material within narrow scope of application temperature, can get same content high precision as extended type |
