Differential Pressure Switch Series 1950
Explosion-Proof, Set Points from 0.07″ to 85″ W.C. Repetitive Accuracy Within 2%
Explosion-Proof Differential Pressure Switch Series 1950 combines the best features of the popular Series 1900 Differential Pressure Switch with an integral explosion-proof and weather-proof housing, making it an exceptional value for either application. Series 1950 Explosion-Proof Differential Pressure Switch is C.E., U.L. and C.S.A. listed, and FM approved for use in Class I Groups C and D, Class II Groups E, F, and G and Class III hazardous atmospheres (NEMA 7 & 9). Weather-proof 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 of the Series 1950 Explosion-Proof Differential Pressure Switches offer set points from 0.03 to 209 (0.8 to 508 mm) w.c. and from 0.5 to 50 psi (3.4 to 345 kPa). The unit is very light and compact, about half the weight and bulk of other explosion-proof or weather-proof switches with separate enclosures.
