Overview

Product Model: YX-100B Theme Features: The explosion-proof category of the instrument is Class II explosion-proof type, Class B T4 group, and its symbol is Ex instrument. It is suitable for measuring non crystalline, non solidified explosive mixtures or various non explosive media pressure instruments in places with explosive hazards. When used in conjunction with electrical devices (such as relays and contactors) with corresponding explosion-proof performance or corresponding safety measures, it can achieve automatic control and signaling (alarm) of the controlled system. Manufacturer: Hongqi Instrument Co., Ltd
