Series 1950G Explosion-Proof Differential Pressure Switch combines the best
features of the popular Dwyer® Series 1950 Pressure Switch with the benefit of natural
gas compatibility. Units are rain-tight for outdoor installations, and are UL listed for use
in 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 and
Class III atmospheres. IECEx Ex db IIB+H2 T6 (-40°C<Ta<+60°C). The 1950G is very
compact, about half the weight and bulk of equivalent conventional explosion-proof
switches.
Easy access to the SPDT relay and power supply terminals is provided by removing
the top plate of the aluminum housing. A supply voltage of 24 VDC, 120 or 240 VAC
is required. A captive screw allows the cover to swing aside while remaining attached
to the unit. Adjustment to the set point of the switch can be made without disassembly
of the housing.
