Summary

The ZENER BARRIER is an important device for connecting primary instrument with secondary instrument for protecting electronic instrument as an intrinsically safe explosion-proof system. It limit the power enter hazardous area by its inner protection component. So that ensure the intrinsically safe for primary instrument and protect the field device and worker fromdanger.

Various types are available for transmitter, electropneumatic final controlling element, thermocouple and resistance bulb, and can be combined with the field instrument mounted in a hazardous area to operate the measuring instrument as an intrinsically safe explosion proof system. It is applicable to automatical procss control in industrial moderniztion, such as, oil field, chemical industry, medcine industry, vessel industry and so on.
