Hermetically Sealed Differential Pressure Detectors

About Hermetically Sealed Differential Pressure Detectors

SOR hermetically sealed differential pressure detector models feature weatherproof and explosion proof protection. The detectoring capsule isolates the contacts from moisture and corrosive environments and virtually eliminates problems associated with these conditions. They are ideal for a variety of applications because the electrical detectoring elements are hermetically sealed in a steel capsule that is certified through global agency listings as an explosion proof snap detector. The highest level of explosion proof rating is standard.
