Pressure Monitoring
Differential Pressure / Air Velocity Transducer
Product Overview
PX3
The PX3 transducer can measure either air pressure or velocity with the flip of a switch.
Patent Pending
The PX3 is available in three installation configurations: duct, panel or universal. Duct and
50
panel models have two pressure and velocity options: 0-1 in. WC / 0-3,000 ft/min or
1-10 in. WC / 3,000-6,000 ft/min with four field-selectable sub-ranges. The universal

Velocity with VFXP Probe
For velocity applications, use the VFXP Series air velocity/measurement probe or AA18,
AA19 or AA20 velocity pitot tubes. For use with the PX3P (panel) and PX3U (universal)
models in Velocity mode only. Sold separately.
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 installation 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.
