Series 616W Differential Pressure Transmitter
Specifications - Installation and Operating Instructions
Fig. A
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.

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
resistance. 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.

2. Position: A vertical position, with the pressure connection pointing
down, is recommended. That is the position in which all standard models
are spanned and zeroed at the factory. They can be used at other
angles, but final spanning and zeroing must be done while transmitter is
in that alternate position.
3. Pressure Connections: Two integral barbed tubing connections are
provided. They are dual-sized to fit both 1/8˝ and 3/16˝ (3.2 and 4.8 mm)
I.D. tubing. Be sure the pressure rating of the tubing exceeds that of the
operating range. On ranges over 20 psi, we recommend use of a suitable
hose clamp to assure the integrity of the connection.
ELECTRICAL CONNECTIONS
CAUTION: Do not exceed specified supply voltage ratings.
Permanent damage not covered by warranty will result. This unit is
not designed for 120 or 240 volts AC line operation.
Electrical connections are made to the terminal block located on the
inside of the transmitter. Terminals are marked 1, 2, 3 and 4. See Fig. B.
Determine which of the following circuit drawings applies to your
application and wire accordingly.
Fig. B
Wire Length - The maximum length of wire connecting transmitter and
receiver is a function of wire size and receiver resistance. Wiring should
not contribute more than 10% of the receiver resistance to total loop
resistance. For extremely long runs (over 1000 feet), choose receivers
with higher resistance to minimize size and cost of connecting leads.
Where wiring length is under 100 feet, hook-up wire as small as 22 AWG
can be used.
2-Wire Operation - An external power supply delivering 10-35 VDC with
minimum current capability of 40 mA DC (per transmitter) must be used
to power the control loop. See Fig. C for connection of the power supply,
transmitter and receiver. Note the jumper between terminals 3 and 4.
The range of appropriate receiver load resistance (RL) for the DC power
supply voltage available is expressed by the formula.
RLMax = Vps - 10V
20mA DC
Shielded two wire cable is recommended for control loop wiring. If
grounding is required, use the negative side of the control loop after the
receiver. Otherwise, in 2-wire operation it is not necessary to observe
polarity of control loop connections.
