B2E Series Diaphragm explosion proof pressure controller


◆ overview

B2E diaphragm explosion-proof pressure controller   comply with GB3836. 1-2010 electrical equipment for explosive gas environment Part 1: General requirements;

Gb3836.1-2010 electrical equipment for explosive gas atmospheres Part 2: Flameproof "d"; Gb3836.1-2010 electricity for explosive gas environment

Gas equipment Part III: Design of increased safety "e" according to relevant regulations. It is an explosion-proof and increased safety composite explosion-proof structural pressure controller

Explosion mark is exde iict6 GB; The electrical switch is exdiic GB (flameproof type) and the shell is ELIC (increased safety type). Suitable for factory with II

A. Class IIB and IIC T1 ~ T6 explosive gas zone 1 and 2 explosive dangerous places.

B2E diaphragm explosion-proof pressure controller is mainly used in metallurgy, chemical industry, machinery, electric power and other industries to control the pressure of gas and hydraulic equipment

Monitoring, alarm, interlocking protection, etc. to realize the process automatic control of the system.
