SOR hermetically sealed differential pressure switch models feature weatherproof and explosion proof protection. The switching 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 switching elements are hermetically sealed in a steel capsule that is certified through global agency listings as an explosion proof snap switch. The highest level of explosion proof rating is standard.
