1. Introduction:

Thermocouple wire is usually used to connect thermocouple and display-controled meters in order to lower the inaccuracy caused by temperature change on the connections.

2. Construction:  
Conductor: original thermocoupole alloy material, in solid wire or strand wires
Insulation Layer:
Fiberglass              (ambient temperature range 0-300ºC
PVC                       (ambient temperature range 0-105ºC)
PFA                  (ambient temperature range 0-260ºC)
Silicone rubber   (ambient temperature range 0-180ºC)
Jacket layer materials: fiberglass, PVC, PFA, silicone rubber
Galvanized layer: stainless steel, tinned brass

3.Standard: conforms to IEC584 standard.

4. Color Code:Table 1

4, CALIBRATION TOLERANCE
                                                       
Thermocouple extension wire type available: KX, JX, TX, EX, NX, RX,SX and other compensating
cable like KCA, KCB and so on.
Besides those wires, we can also produce according to your demand.

1  Thermocouple Types: K, J, E, T, N, S          RTD: Cu, Ni

2  Conductot dimension:
2*7/0.3 means 2 cores,  each core includes 7 strands wire,
each wire diameter is 0.3mm, more example: 2×7/0.2, 2×4/0.65, 2×1/0.3 etc.
Other way to symbol the conductor dimensions:
Conductor square meter: 0.25mm²
AWG standard (see*Table 2)
