About Explosion Proof Pressure Switches
The process instrumentation industry standards define devices rated “explosion proof” as those with an enclosure capable of containing an explosion of a specified gas, vapor or dust which may occur within it. Agency listings are required in order to market any pressure switch device as “explosion proof.” See below for our selection of explosion proof pressure switches.
