Wire and Cable
Compensation wire for thermocouple. Compensation cable

Compensation wires and cables are one or more pairs of wires or cables with insulation layers that have the same thermoelectromotive force value as the matched thermocouples within a certain temperature range (including normal temperature). Use them to connect thermocouples and measuring devices In order to compensate for the error caused by the temperature change at the connection between them and the thermocouple, the compensation wire and compensation cable are divided into two types: extension type and compensation type.


■ Executive standard: GB / T4989-94 JB / T7495-94

■ Use characteristics:
1. Working temperature:
Heat resistance: up to 200 ° C and 260 ° C. General use: up to 70 ° C and 105 ° C.

2. Minimum ambient temperature:
Fluoroplastic insulated and sheathed cable: fixed laying -60 ℃, non-fixed laying -20 ℃
PVC insulated and sheathed cable: fixed laying -40 ℃, non-fixed laying -15 ℃

3. Allowable bending radius:
Polyvinyl chloride insulated and sheathed non-armored cable is not less than 6 times the outer diameter of the cable Times

Note:
1.Precision grade is represented by S
2. Add "-R" at the end of the original model when the conductor is a multi-stranded soft core.
3. The shielding layer can also be wrapped with composite aluminum tape (P3) and composite copper tape (P2).
4. To be flame-retardant, add "ZR-" before the original model
