Product Desciption

Thermocouple Extension Cable RTD Type Fiberglass Insulated Stainless Steel 304 Sheath

In actual temperature measurement, usually there are long measuring distance with the measuring device, a thermocouple compensation wire is generated to compensate the temperature difference caused by the temperature change between the measuring device and the thermocouple connecting piece.

The compensation cable has the following advantages: improving thermocouple temperature measurement line physical properties and mechanical properties; improving the measurement line flexibility and making the connection convenient by using multi-strand core or small-diameter compensation wire; easy to shield external interference; reducing measuring lines cost.

Thermocouple Cable Grade

A:Extension Grade Cable

Whose wire composition is totally as the same as the thermocouple wire, remarked by the letter"X"after the thermocouple symbol number, such as"KX""JX""TX"

B:Compensation Grade Cable

Whose wire composition is different from the thermocouple wire, but its wire electromotive force (EMF) value is the same as thermocouple wire only at 0-100ºC or 0-200ºC. It remarked by the letter"C"after the thermocouple symbol number, such as"KC""JC""TC"

For cost consideration, when the tested temperature under 200ºC, compensation grade cable is preferred. But compensation grade cable will occur enormous tested temperature value deviation if the tested temperature above 200ºC. The higher the tested temperature, the greater deviation be.
For compensation grade cable, the max testing temperature is less than 200ºC, the bigger the cable, the smaller the signal loss.
Extension cable and compensation cable comparison:

Performance	Extension Grade	Compensation Grade
Material	Same as thermocouple	Different from thermocouple
EMF Value Feature	Same as the thermocouple's at certain temperature range	Same as the thermocouple's
Deviation Curve	Nonlinear, varies with temperature	Linear
Working Temperature Range	Limited(usual at 100ºC)	Unlimited(depend on insulation material temperature bearing)
Line Resistance	Low resistance	High resistance
Compensation Contact Interference	Different contactor material may cause interference	None
Accuracy	Low	High
Price	Low	High(about 1-2 times higher)
