Product Overview
Description
Application
YX-160-B explosion-proof electric contact pressure gauge has excellent explosion-proof performance, thus it can avoid influence from spark or arc during normal working process, it can not only stand explosive pressure generated by mixed explosive gas inner the shell, but also stop the heat spreading outside, and just spreads slowly outside along with the shell adjoining gap which will not cause explosion. Working principle Based on elastic deformation of detection element (bourdon tube), drive joint contact act (on or off) through mechanical driving to control system circuit open or close, finally realize automatic control alarm and field indication.
