Dwyer Differential Pressure Switch 1950 Series

Explosion proof micro differential pressure switch

Small size, low price, explosion-proof, all-weather protection type

The 1950 explosion-proof differential pressure switch combines all the performance of the 1900 series differential pressure switch, and is equipped with explosion-proof or all-weather protective casing, making it more widely used and of higher application value. It has CE, UL, CSA, and FM certifications, with explosion-proof levels of 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). The all-weather protective casing is equipped with drainage plugs and O-ring seals, making it easy to connect wires by opening the front cover plate. The set point can be adjusted outside the protective casing. There are 12 models to choose from, ranging from 0.03 “to 220” inches of water column (7.5 to 5000PA) and from 0.5 to 50psi (0.035 to 3.5Bar). The 1950 explosion-proof differential pressure switch has a small volume and light weight, which is half the size and weight of other explosion-proof switches.

Warning: Can only be used with air or compatible gases. When used in hazardous situations and under single positive pressure, special ventilation and exhaust must be carried out.
