Dwyer Series 607 Differential Pressure Transmitter 607-1 607-3B
607-8 Series 608 Series 668 Low Rnage 0 To 25" w.c
Description The Dwyer Series 607 Differential Pressure Transmitter
converts positive, negative (vacuum) or differential pressures of
clean, dry air or other non-conductive, non-corrosive gases into a
standard two wire, 4-20 mA output signal. Several factory
calibrated models are available with ranges from 0-.10″ W.C. to
0-25″ W.C. All models employ a variable capacitance transducer with
a micro-machined, ultra thin silicon diaphragm enabling precision
measurement and control of very low pressures. Because no epoxies
or other organics are used to seal the sensor, performance is
exceptionally stable and drift free. It is also highly resistant to
overpressure, shock and vibration. See specifications for complete
details.

Installation
1. Location: Select a clean, dry location free of excess vibration
where the temperature of the unit with be between -20 and 160°F.
Distance from the receiver is limited only by total loop
resistance. See “ Electrical Connections”. The tubing supplying
pressure to the transmitter can be run practically any distance.
Long tubing lengths will not affect accuracy but response time will
be increased slightly.
2. Position: The Series 607 Transmitter is not position sensitive.
However, it is recommended that you avoid mounting with pressure
connections pointing up because of the chance of condensed moisture
entering the interior. Moisture can also be avoided by routing
tubing with a low point just ahead of the transmitter.
3. Mounting: Attach to mounting surface with two #8 or #10 screws
in the mounting slots provided.
4. Pressure connections: The Series 607 Transmitter is shipped with
a short length of tubing installed between the ports to keep the
interior clean. Remove it and discard after unit is mounted.
Connect positive (above atmospheric) pressure to port marked “HIGH
and vent the “LOW” port. Connect negative (vacuum) pressure to port
marked “LOW” and vent the “HIGH” port. For differential pressures,
connect the higher one to the “HIGH” port and the lower one to the
“LOW” port.
Electrical Connection
Caution: Do not exceed the specified supply voltage rating. Permanent
damage, not covered by warranty, may result. This unit is not
designed for AC voltage operation.
Electrical connections to the Series 607 Transmitter are made to
the two screws on the terminal strip labeled + and -. If polarity
is inadvertently reversed, the loop will not function properly but
no damage will be done to the transmitter because of internal
circuit protection. An external power supply delivering 12 to 36
VDC must be used to power the control loop in which the transmitter
is connected. Refer to Figure B for connection of the power supply,
transmitter and receiver. The power required to generate the 4-20
mA output signal depends on the loop resistance of the circuit and
is proportional to the resistance according to the graph and
formula in Figure C. The maximum length that can be used in the
current loop is a function of wire size and receiver resistance. A
shielded two conductor cable is recommended for control loop
wiring. Make sure the total loop resistance is within the operating
region as shown in Figure C.
