First, the characteristics and uses of this high temperature compensation cable

The compensation cable for thermocouple of intrinsically safe explosion-proof temperature measuring system is a cable composed of multiple pairs of intrinsically safe explosion-proof temperature measuring system with compensation wires. Besides the performance of other compensation cables, it also has explosion-proof safety performance. It is suitable for the environment with explosion risk and the occasion of high explosion-proof safety performance. The cold end of the extended explosion-proof thermocouple and the explosion-proof thermometer are connected to form the intrinsically safe explosion-proof temperature measuring system.
