Dwyer Instruments 1950G-0-B-120-NA | Differential Pressure Switch | Explosion Proof | .15-.50in w.c. | 1950G Series
The Dwyer 1950G Series presents an explosion-proof differential pressure switch, offering set points from .03 to 20 in w.c. It integrates the standout features of the popular Dwyer Series 1950 Pressure Switch with natural gas compatibility. These units are designed for outdoor use, featuring rain-tight construction, and hold UL listings for various atmospheres. They comply with Directive 2014/34/EU (ATEX) for CE ATEX II 2G Exd IIB+H2 T6 and are CSA & FM approved for IECEx Ex d IIB+H2 T6 (-40°C < Ta < +60°C).
Despite their robustness, the 1950G series maintains a compact form, weighing about half as much as equivalent conventional explosion-proof switches. Accessing the SPDT relay and power supply terminals is easy with the removal of the top plate of the aluminum housing. Operating with a supply voltage of 24 VDC, 120, or 240 VAC, these switches feature a captive screw for adjusting the set point without housing disassembly.
