The Series 616D Differential Pressure Transmitter senses the
pressure of air and compatible gases and sends a standard 4-20 mA
output signal. The 616D housing is specifically designed to mount on a
35 mm DIN rail in a panel. This mounting style allows for several units to
be mounted closely together reducing required space. A wide range of
models are available factory calibrated to specific ranges as listed in the
chart below. The span and zero controls are for use when checking
calibration. They are not intended for re-ranging to a significantly
different span. Versatile circuit design enables operation in 2-wire
current loops.
For applications requiring direct pressure readings or percent of full span
output, the optional Model A-701 Digital Readout makes an ideal
companion device. It provides a bright red 0.6˝ high, 3-1/2 digit LED
display while supplying power to the Series 616D transmitter. For
additional information on these and other transmitters, see the Dwyer
Instruments, Inc. full line catalog.

Series 616D Transmitter Models and Ranges
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 48.9°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 pressure connections 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.
Pressure Connections
Two integral barbed tubing connections are provided. They are dual-
sized to fit 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.
