Description

Compensating wire and cable for thermocouple

Product features and uses:
PVC insulated and sheathed compensating wires and cables for thermocouples have excellent moisture-proof, wear-resistant and flame-retardant properties; The continuous extrusion process is adopted for the compensation conductor and cable with Fluoroplastic insulation and sheath for heat resistance, which has excellent properties of high temperature, low temperature, acid and alkali resistance, oil resistance, wear resistance, aging resistance, waterproof and non flame retardation.
Thermocouple compensation wires and cables for intrinsically safe explosion-proof temperature measurement system adopt low capacitance and low inductance structure. In addition to the performance of common thermocouple compensation wires and cables, they also have explosion-proof safety performance. They are suitable for the environment with explosion risk and high requirements for explosion-proof safety performance. The cold end of explosion-proof thermocouple is extended to connect with explosion-proof temperature measuring instrument, Constitute the intrinsic safety thermocouple temperature measurement system.
