Dwyer Instruments 616W Series Installation And Operating Instructions

The Series 616W Differential Pressure Transmitter senses the
pressure of air and non-combustible, compatible gases and sends a
standard 4-20 mA output signal.
All models, including those featuring LCD digital read-out, are factory
calibrated to specific ranges, as listed in the chart on the next page.
Positive, negative and differential pressures can be measured within a
full span accuracy of ±0.25%. This weatherproof unit is enclosed in a
polycarbonate case, rated (IP66/NEMA 4X).
The Span and Zero controls are for use when checking calibration. They
are not intended for re-ranging to a significantly different span.
