| Positive, negative and
differential pressures can be measured within a full span accuracy
of ± 0.5 with the Dwyer Series 616W Differential Pressure
Transmitter. Units are enclosed in a polycarbonate case, rated NEMA 4X
(IP66) and operate by sensing the pressure of air and compatible gases
then sending a standard 4-20mA output signal. Versatile circuit design
enables operation in 2,3,4 wire current loops, and a wide range of
models are available factory calibrated to specific ranges. The span
and zero controls are for use when checking calibration. They are not
intended for re-ranging to a significantly different span. The LCD (as
shown above) allows local indication of pressure, if LCD is not
needed, drop from model number.
