One, the safety of high temperature compensation cable product characteristics and use

Intrinsically safe explosion-proof temperature measuring system thermocouple compensation cable is composed of several pairs of intrinsically safe explosion-proof temperature measuring system compensation cable, in addition to other compensation cable performance but also explosion-proof safety performance. It is suitable for explosion-proof dangerous environment and occasions with high requirements of explosion-proof safety performance. The extension of explosion-proof thermocouple cold end is connected with the explosion-proof thermometer table to form an essential safety explosion-proof temperature measuring system.

Two, implementation standards
