Dwyer, 616W-7-LCD, Series 616W Differential Pressure Transmitter, Range 0-200" w.c., Max
Design enables operation in 2-wire current loops
Pressure 29 psig., With Liquid Crystal Display NEMA 4X Enclosure, 0.25 FS Accuracy Positive, negative and differential pressures can be measured within a full span accuracy of 177 0.25 with the Series 616W Differential Pressure Transmitter
The LCD allows local indication of pressure.
The span and zero controls are for use when checking calibration
They are not intended for re-ranging to a significantly different span
Unit is 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
