SERIES 1950 EXPLOSION-PROOF DIFFERENTIAL PRESSURE SWITCH SERIES 1950 EXPLOSION-PROOF DIFFERENTIAL PRESSURE SWITCH Set Points from .03 to 20 in w.c., Explosion-Proof And Weatherproof Series 1950 Explosion-Proof Differential Pressure Switch Combines The Best Features Of The Popular Dwyer® Series 1900 Pressure Switch With an Integral Explosion-Proof And Weatherproof Housing, Making it An Exceptional Value For Either Application. It is CE, UL and CSA listed, FM Approved For use in Class I, Div 1, Groups C and D, Class II Groups E, F, and G and Class III hazardous atmospheres (NEMA 7 & 9), Raintight NEMA 3 (IP54). Weatherproof features include a drain plug and O-ring seal in cover. Electrical connections are easily made by removing front cover. For convenience the set point adjustment screw is located on the outside of the housing. Twelve models offer set points from .03 to 20 in w.c. (0.0075 to 5 kPa) and from .5 to 50 psi (0.035 to 3.5 bar). The unit is very light and compact — about half the weight and bulk of other Explosion-Proof or Weather-Proof Switches with Separate Enclosures. CAUTION: For Use Only With Air or Compatible Gases. Applications With Hazardous Atmospheres and a single Positive Pressure May Require Special Venting.

Series H3 Explosion-Proof Differential Pressure Switch

Get Price Quote

Series H3 Explosion-Proof Differential Pressure Switch Explosion-proof, heavy duty, industrial unit has 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 piston-type motion transfer, the Series H3 utilizes a rotary motion transfer shaft that prevents a change in total pressure from causing a setpoint shift. Unit yields deadbands approximately 5% of range, with zero setpoint shift due to variation in working pressures. Friction is minimized and repeatability increased by allowing range spring to act directly on diaphragm plate. Rolling diaphragm design maintains constant effective area to further reduce friction. Diaphragm is allowed to "seat", allowing application of full rated pressure, up to 1500 psi (103 bar), on either high or low pressure port, without damage. Special over-travel feature prevents overtightening of range adjust screw. Choose optional 316SS chamber for water and water-based fluids or harsher applications. Product Applications : Water flow proving with an orifice plate. Differential pressure across chiller. : Perfect for monitoring differential water pressure on filters, chiller coils, and flow elements.
