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.
The PX3 is available in three installation configurations: duct, panel or universal. Duct and
50
panel models have two pressure and velocity ranges: 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

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 sensor port A to the rear brass barb marked as "-" on the underside of the
device housing.
b. Connect sensor port B to the probe in the back of the device housing.
Panel mount tubing configuration:
a. Connect sensor port A to the rear brass barb marked as "-" on the underside of the
device housing.
b. Connect sensor port B to the front brass barb marked as "+" on the underside of the
device housing.
