Dwyer Instruments 1950P-25-2F | Differential Pressure Switch | 4-25 psid;1/8" NPT F;Explosion Proof
The well-liked Dwyer® Series 1900 Pressure Switch's best characteristics are combined with an integrated explosion-proof and weatherproof casing to create the Series 1950 Explosion-Proof Differential Pressure Switch, which is a fantastic bargain for any application. It is 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). It is also listed by the CE, UL, and CSA. It is also raintight NEMA 3 (IP54). An O-ring seal in the cover and a drain plug are examples of weatherproof characteristics. Removing the front cover makes it simple to make electrical connections. The set point adjustment screw is conveniently situated on the housing's exterior. Set points ranging from 03 to 20 in w.c. (0.0075 to 5 kPa) and from 5 to 50 psi (0.035 to 3.5 bar) are available in twelve variants. About half the weight and size of typical explosion-proof or weather-proof switches with separate casings are contained in this incredibly light and compact item.
