The thermocouple compensating wire and compensating cable are a pair of insulated wires with the same nominal value of the matching thermoelectromotive force in a certain temperature range (including high temperature cable and normal temperature), and are used to connect the thermoelectric Even with the measuring device to compensate for the error caused by the temperature change at the junction with the thermocouple. This product is suitable for electrical connection between various thermocouples with temperature numbers S, K, E, T, J and N and temperature display instruments to improve measurement accuracy.2: Conditions of use High temperature compensation wire cable for thermocouple:
(1) Working temperature: heat resistant: up to 200 ° C and 260 ° C，silicone rubber cable;
Generally used: up to 70 ° C and 105 ° C.
(2) Minimum ambient temperature: fluoroplastic insulated and sheathed cable: fixed laying -60 ° C, non-fixed laying -20 ° C;
PVC insulated and sheathed cable: fixed laying -40 ° C, non-fixed laying -15 ° C.
(3) Minimum bending radius: PVC insulated and sheathed cable non-armored cable is not less than 6 times the outer diameter of the cable, fluoroplastic insulated and sheathed non-armored cable is not less than 10 times the outer diameter of the cable, armored cable Not less than 12 times the outer diameter of the Heat Trace Cable.
