ZRC-KX-HA-FF46P2-2×2×1.5 Compensating Conductor Cable Application:
Thermocouple compensating conductors and cables with polyvinyl chloride insulation and sheath offer excellent moisture resistance, wear resistance, and flame-retardant properties; heat-resistant compensating conductors and cables with fluoro-plastic insulation and sheath are produced using continuous extrusion technology.
Intrinsically safe explosion-proof temperature measurement systems use thermocouple compensation wires and cables with low capacitance and low inductance structures. In addition to the performance of standard thermocouple compensation wires and cables, they also possess explosion-proof safety features, forming the intrinsic safety thermocouple temperature measurement system.
