QUICK INSTALL
Observe precautions for handling static sensitive
devices to avoid damage to the circuitry that
is not covered under the factory warranty.
1. Mount the PXR onto DIN rail.
2. Congure the tubing for dierential or static pressure monitoring.

PXR
OPERATION
PX Series devices employ ceramic capacitive sensors and sophisticated temperature
compensation circuitry to achieve accurate pressure readings in dry media
applications. For best results, allow an initial warm-up period to ensure accuracy at
the lowest pressure ranges.
The PXR has a ZERO pushbutton to reset the output and display to zero pressure.
Press and hold the ZERO pushbutton for 2 seconds or provide contact closure on the
“AUX ZERO” terminal. To protect the unit from accidental zero, this feature is enabled
only when the detected pressure is within about 0.1 in. W.C. (25 Pa) of the factory
calibration. The optional LCD displays the current reading and the selec ted units.
“SET” appears each time a selection is made. “OVER” appears when the measured
pressure is over the device’s range.
INSTALLATION
Observe precautions for handling static sensitive
devices to avoid damage to the circuitry that
is not covered under the factory warranty.
Disconnect power to the panel.
1. Select a location in the panel, near the area to be monitored. Mount the PXR onto
DIN Rail.
INSTALLATION GUIDE
Wire the PXR: connect the transmitter to the control system and the power supply
as indicated below. Optional: Connect the ZERO terminals to the digital output
(contact closure) of the control system.
