DWYER 1950-1-2F PRESSURE SWITCH 0.4 - 1.6 "H2O Model 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.

The unit is very light and compact - about half the weight and bulk of other explosion-proof or weatherproof switches with separate enclosures. 1950-1-2F : Differential pressure switch, range .4-1.6" w.c., approx. deadband @ min. set point 0.15, approx. deadband @ max. set point 0.20.
