Dwyer Wet/Wet Differential SPDT Pressure Switch, 1/4" FNPT, NEMA 4X (2.5 - 10 PSI)

Wet/Wet Differential SPDT Pressure Switch, 1/4" FNPT, NEMA 4X (2.5 - 10 PSI) The Series DX Wet/Wet Differential Pressure Switch makes a contact output based on the differential between two pressure sources. Wetted materials of brass and fluoroelastomer are suitable for use with most gases and water based solutions. The switch can be used for low differential pressure indication with set point on a decrease of pressure as low as 1 psid (0.07 bar). Differential set point ranges are available from 2.5 to 75 psid (0.17 to 5.17 bar) on increasing differential pressure and 1.0 to 67 psid (0.07 to 4.62 bar) on decreasing differential pressure. Unit features a high static pressure rating of 200 psig (13.8 bar). Weatherproof, UL type 4X, enclosure for dust laden, outdoor, or wash-down installation environments. Externally adjustable set point, integral mounting flange and a removable electrical terminal block for quick and easy installation. Applications: Indicating filter condition Proof of flow indicator monitori...
