Explosion-proof differential pressure switch | range .4-1.6″ w.c. | approx. deadband @ min. set point .11 | approx. deadband @ max. set point .29
Series 1950G Explosion-proof Differential Pressure Switch
Series 1950G Explosion-Proof Differential Pressure Switch combines the bestfeatures of the popular Dwyer® Series 1950 Pressure Switch with the benefit of naturalgas compatibility. Units are rain-tight for outdoor installations, and are UL listed for usein Class I, Groups A, B, C, & D; Class II, Groups E, F, & G and Class III atmospheres,Directive 2014/34/EU (ATEX) Compliant for 2813 II 2G Ex db IIB+H2 T6, CSA& FM approved for Class I, Div. 1, Groups B, C, D; Class II, Div. 1, Groups E, F, G andClass III atmospheres. IECEx Ex db IIB+H2 T6 (-40°CEasy access to the SPDT relay and power supply terminals is provided by removingthe top plate of the aluminum housing. A supply voltage of 24 VDC, 120 or 240 VACis required. A captive screw allows the cover to swing aside while remaining attachedto the unit. Adjustment to the set point of the switch can be made without disassemblyof the housing.
