Product Description

The Dwyer 1950G ATEX Differential Pressure Switch is a compact switch, designed for air and compatible, combustible gasses. Including Natural gas. Suitable for performing switching functions at low differential pressures in hazardous area, with set point ranges from 0.07 to 20 in wc.

 

The Dwyer 1950G ATEX Differential Pressure Switch is powered by 24VDC power supply as standard, 120 or 240VAC options are available. Fluidic can also offer non-powered ATEX differential pressure switches, for example the Dywer AT21823.

The single-pole, double-throw (SPDT) switch set-point can be adjusted via a screw on the outside of enclosure, meaning the Exd housing does not have to be dismantled to adjust set-point. Switch can be wired to Normally Open(NO) or Normally Closed(NC).

 

Fluidic can supply the 1950 G switch pre-set, against a calibrated reference, to suit user requirements.

The Dwyer 1950G ATEX Differential Pressure Switch has ATEX approval to Group II 2G Exd IIB + H2 T6.
