20AWG PVC Thermocouple Extension Wire Type K / J / E / N / T / R / S / B
Product Description
1. Introduction:
Thermocouple Extension cable 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)
TF (ambient temperature range 0-350ºC)
Silicone rubber (ambient temperature range 0-180ºC)
Jacket layer materials: fiberglass, PVC, TF, silicone rubber
Galvanized layer: stainless steel, tinned brass
3.Standard: conforms to IEC584 standard.
4. Color Code:Table 1
