Series 1000E Explosion-Proof Diaphragm Operated Pressure Switch

Brand: Dwyer Instruments, LLC
Does not ship to United States
The Series 1000E Explosion-Proof Diaphragm Operated Pressure Switch has the same rugged construction as used in Series 1000W plus explosion-proof design are combined in this new unit.

UL listed for Class I, Groups A, B, C & D; Class II, Groups E, F & G.

Bellville spring movement permits mounting of control in any position and helps prevent contact chatter. High over-pressure protection and vibration resistance are also featured.
Features
  • Weatherproof housing is ideal for a wide variety of applications where dust or water is present
  • Spring movement design provides for control in any mounting position and prevents contact chatter reducing false or inconsistent switching
  • UL listed to support rigorous process applications and regulations
