Dwyer Series 616W
Differential Pressure Transmitter
NEMA 4X Enclosure, 0.5% F.S. Accuracy, Ranges from 0-1" w.c. to 0-20 psid
 

Dwyer Series 616WPositive, 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 4-20 mA output signal.
Design enables operation in 2-wire current loops. 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.)
