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.
RL Max = 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.
