Dwyer Series 616KD is a differential pressure transmitter that senses the pressure of air and compatible gases and sends a standard 4 to 20 mA or optional voltage output signal. It has a wide range of models factory calibrated to specific ranges and a single push button that properly adjusts both zero and span. The 616KD is suitable for use in clean, dry mounting locations with temperatures between 20 and 122°F (-6.7 and 50°C). It has two integral barbed tubing connections and can be mounted vertically with pressure connections pointing down.

Differential Pressure Transmitter senses the
pressure of air and compatible gases and sends a standard 4 to 20 mA or optional
voltage output signal. A wide range of models are available factory calibrated to
specic ranges. A single push button properly adjusts both zero and span. New
enclosure enables the 616KD-A/B to be mounted on a 35 mm DIN rail either via its
side or back DIN rail clips.
INSTALLATION
1. Location
Select a clean, dry mounting location free from excess vibration where the
temperature will remain between 20 and 122°F (-6.7 and 50°C). 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 pressure connections pointing down, is recommended.
That is the position in which all standard models are calibrated at the factory. Consult
factory for other position orientations.
3. Pressure Connections
Two integral barbed tubing connections are provided. They are dual-sized to t both
1/8 and 3/16˝ (3.12 and 4.76 mm) I.D. tubing. Be sure the pressure rating of the
tubing exceeds that of the operating ranges.
4. Electrical Connections:
Electrical connections are made to the terminal block located on the top of the
transmitter. Terminals are marked 1, 2, 3 and 4 as shown below. Determine which
of the following circuit drawings applies to your application and wire accordingly.
Shielded cable is recommended. Ground the shield at the power supply end only.

ZERO ADJUSTMENT
A single push button is provided to zero the transmitter. For A and B models a side
mounted zero push button is provided in addition to the standard push button. The
zero calibration can be set by applying zero pressure to both the pressure ports and
pressing the zero button for 2 seconds. Span is factory calibrated to the range speci-
ed on the label. There is no user span adjustment necessary.
CHANGING OUTPUT SIGNAL
To change output signal see dipswitch settings in Figure 3 – OUTPUT SIGNAL DIP-
SWITCH SETTINGS.
MAINTENANCE/REPAIR
Upon nal installation of the Series 616KD no routine maintenance is required. The
Series 616KD is not eld serviceable and should be returned if repair is needed. Field
repair should not be attempted and may void warranty.
