EXPLOSION-PROOF DIFFERENTIAL PRESSURE SWITCH SERIES H3

The Series H3 Explosion-Proof Differential Pressure Switch is a heavy duty, industrial unit with a unique new design which provides sensitivity to differential pressures as low as 10 inches of water (254 mm w.c.), yet handles total pressure of 1500 psi (103 bar). Unlike common differential pressure switches that use a pistontype motion transfer, the Series H3 utilizes a rotary motion transfer shaft that prevents a change in total pressure from causing a set point shift.
