PXR INSTALLATION GUIDE
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 selected 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.
2. Determine the length of tubing needed for differential or static pressure. Configure
as shown:
