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.

we need atex certificate for 1950-G instrumement
ATEX certification comes standard on the 1950G series. We do have certain models that come with other approvals (and not ATEX). These models will end in -CCC, -KC, -PESO, or -NA. As long as the model you purchase does not end with one of these, it will be ATEX approved.
