PT100 PFA 20AWG Rtd Extension Cable Thermocouple Cable

 

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)
FEP                  (ambient temperature range 0-260ºC)
 Silicone rubber   (ambient temperature range 0-180ºC)
Jacket layer materials: fiberglass, PVC, FEP, silicone rubber
Galvanized layer: stainless steel, tinned brass

3.Standard: conforms to IEC584 standard.
