Pressure Switches Survive In Harsh And Hazardous Locations

Small, rugged pressure switches for use in Division I, Class I and Class II hazardous and volatile locations, these three switches can handle high pressures, shock, and vibration in industrial applications. The switches are the 9671X, a single setting, field adjustable vacuum switch with an operating range of 1'' to 30'' of Hg; the 9681X, a pressure switch with operating ranges of 5 to 500 psi; and the 9692X, a pressure switch with an operating range of 500 to 7,500 psi. All three models can be safely adjusted during operation and available as single SPDT switches. An option of two SPDT switches to simulate DPDT operation is also available. Other features include tamper proof covers, sealed piston sensors, and 300 Series stainless steel process fittings. Enclosures are anodized aluminum rated NEMA 4, 7 and 9. Units are easy to install with a 1/4'' NPT female pressure connection and a 1/2'' NPT male conduit connection with free leads for easy wiring.
