1950G-00-B-24-NA

1950G-00-B-24-NA is a series 1950G explosion-proof differential pressure switch combines the best features of the popular Dwyer® series 1900 pressure switch with the benefit of natural gas compatibility. Units are rain-tight for outdoor installations. 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 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. Typical applications include natural gas applications, process applications and all-weather applications.
