Dwyer Instruments 616WL-2 Installation And Operating Instructions

The Dwyer Series 616WL Differential Pressure Transmitter senses the
pressure of air and non-combustible, compatible gases and sends a stan-
dard 4-20 mA output signal.
All models, including those featuring the 3 digit LCD digital read-out, are
factory calibrated to specific ranges as listed in the chart below.
Positive, negative and differential pressures can be measured within a full
span accuracy of ±0.50%. This weatherproof unit is enclosed in a poly-
carbonate case, designed to meet (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.

INSTALLATION

1. Location: Select a clean, dry mounting location free from excess
vibration where the temperature will remain between 20 and 120˚F (-6.7
and 49˚C). Distance from the receiver is limited only by total loop resis-
tance. See Electrical Connections below. The tubing supplying pressure to
the instrument can be practically any length required, but long lengths will
increase response time slightly.
