Product Overview

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 
panel models have two pressure and velocity options: 0-1” WC / 0-3,000 ft/min or  
1-10” WC / 3,000-6,000 ft/min with four field-selectable sub-ranges. The universal 
model comes in one pressure/velocity range: 0-10” WC / 0-7,000 ft/min with seven 
field-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.

Specifications

Installation, Wiring 

& Configuration

1.   Plan the installation. Panel or duct mount? 

Note: Velocity measurement requires the use of an AA18, AA19 or AA20 pitot tube (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.
