Dwyer Pressure Transmitter Cat#604-3

The Dwyer Series 604A Differential Pressure Transmitter converts air or compatible gas pressure into a standard 4-20 mA output signal for pressure ranges from 0-0.4” up to 0-120˝ w.c. (0-2.54 mm up to 0-304.9 mm w.c.). Each of these models overlap in range so that any range within these limits can be achieved by adjustment of the span and zero controls. Versatile circuit design enables use in 2, 3 or 4-wire current loops.
