YX-160-B Explosion-proof Electric Contact Pressure Gauge

Product name：YX-160-B Explosion-proof Electric Contact Pressure Gauge Manufacturer：Shanghai NO.4 Automation Instrumentation Factory Classification：Pressure gauge > Electric contact pressure gauge Sales manufacturer：Shanghai Automation Instrumentation Co., Ltd Release date：2017-5-5

Brief Description

YX-160-Bexplosion-proof electric contact pressure gauge has excellent explosion-proofperformance, thus it can avoid influence from spark or arc during normalworking process, it can not only stand explosive pressure generated by mixedexplosive gas inner the shell, but also stop the heat spreading outside, andjust spreads slowly outside along with the shell adjoining gap which will notcause explosion.

Workingprinciple

Based on elasticdeformation of detection element (bourdon tube), drive joint contact act (on oroff) through mechanical driving to control system circuit open or close,finally realize automatic control alarm and field indication.
