Dimensions

Product Overview

The PX3 transducer can measure either air pressure or velocity with the ip of a switch.

The PX3 is available in three installation congurations: duct, panel or universal. Duct and

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 eld-selectable sub-ranges. The universal

model comes in one pressure/velocity range: 0-10 in. WC / 0-7,000 ft/min with seven

eld-selectable sub-ranges for pressure and eight for velocity. All variants are available

with and without display. The PX3 has an IP65/NEMA 4 environmental rating and a 5-year

limited warranty.

1. Plan the installation. Panel or duct mount?

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. Congure the internal tubing for the selected installation method as described below.

Duct mount tubing conguration:

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 conguration:

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.
