P7650A/B/U
DIFFERENTIAL PRESSURE TRANSDUCER, DRY MEDIA
APPLICATION
The P7650A/B/U Differential Pressure Sensor measures
static and differential air pressure in duct and panel
applications. It can also measure air velocity using
pressure-velocity pick up tubes P7650L6, P7650L8,
P7650L10, P7650L12, or P7650L14. P7650A/B/U can be
ordered in duct or panel versions and in 0 to 1 in. (0 to
250 Pa) or 0 to 10 in. (0 to 2500 Pa) pressure ranges.
Universal models can be configured for duct or panel and
for 0 to 1 in. (0 to 250 Pa) or 0 to 10 in. (0 to 2500 Pa)
pressure ranges. All variants are available with and
without LCD display. The P7650A/B/U has an
IP65/NEMA 4 environmental rating and a 5-year limited
warranty.

INSTALLATION, WIRING & CONFIGURATION
1. Plan the installation. Panel or duct mount?
Fig. 2.
NOTE: Velocity measurement, shown below, requires the use of a pressure-velocity pick up tube, part P7650L6,
P7650L8, P7650L10, P7650L12, or P7650L14. Length is the number after L in inches, so P7650L6 is 6 inch,
etc. See form 31-00149 for details on installing and configuring the P7650L velocity pick up probes.
Fig. 3.
2. For duct mount applications, thread the probe into
the back of the device housing, as shown in the
dimensional drawing.
3. Configure the internal tubing for the selected instal-
lation method as described below.
Duct mount tubing configuration:
a. Connect the right-side tube to the rear brass
barb marked as “-” on the underside of the device
housing.
b. Connect the left-side tube to the probe in the
back of the device housing.
Panel mount tubing configuration:
a. Connect the right-side tube to the rear brass
barb marked as “-” on the underside of the device
housing.
b. Connect the left-side tube to the front brass barb
marked as “+” on the underside of the device
housing.

4. Mount the transducer (see the screw hole diagram
below).

5. For applications using conduit, remove the cable
gland nut on the bottom of the unit. Thread a stan-
dard 1/2-inch NPT female threaded coupler onto
the body of the cable gland. Connect the opposite
end of the coupler to the conduit.

8. Connect the transmitter to the control system and
power supply as indicated below. Optional: Connect
the ZERO terminals to the digital output (contact
closure) of the control system.

Fig. 8. 3-wire, 0-5 V/0-10 V Voltage Output.
9. Wait five seconds, then press and hold the ZERO
pushbutton for two seconds or provide contact clo-
sure on the AUX ZERO terminal. This will reset the
output and display to zero pressure. For best accu-
racy, press the ZERO button while both ports are
open to atmospheric pressure. To protect the unit
from accidental zero, this feature is enabled only
when the detected pressure is within about 0.1 in.
WC (25 Pa) of factory calibration.
10. Connect desired external tubing to the P7650A/B/U.
P7650A/B/U Series devices employ high performance
sensors and sophisticated temperature compensation
circuitry. The sensor achieves its best accuracy after an
initial warm-up period. During the first few minutes of
operation, readings at zero pressure and the lowest
pressure ranges appear erroneous. Following this initial
warm-up period, the P7650A/B/U device maintains its
specified accuracy and stability.
The LCD momentarily indicates range ‘SET’ when a
selection is made. Pressure is normally indicated on the
display. Units are in inches water column (in. WC),
Pascals (Pa) or kilopascals (kPa) as indicated on the
display. The display shows ‘OVER’ when the pressure is
over range.
