Pressure Monitoring | Dry Media Digital Pressure Transducer

PX3 SERIES

Differential Pressure/Air Velocity Transducer

PX3

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 options: 0-1” WC / 0-3,000 ft/min or
1-10” WC / 3,000-6,000 ft/min with four eld-selectable sub-ranges.
The universal model comes in one pressure/velocity range:
0-10” 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.

Reduce field
failures

Excellent tolerance to overpressure
& vibration reduces field failures

High accuracy

High accuracy digital sensor with
seven selectable pressure and eight
velocity sub-ranges, maintains
calibration and reduces callbacks

Maintenance free

High reliability sensor technology
for long-term, maintenance-free
operation

APPLICATIONS

• Duct static pressure
(Pressure mode)

• Building or room pressure
(Pressure mode)

Reduce setup

Selectable ranges and scales
reduce setup time and number of
models to stock

Water-resistant
housing

IP65/NEMA 4 housing allows for
mounting in wash-down locations

Circuit protection

Circuit protection avoids damage
due to incorrect input wiring

• Filter status
(Pressure mode)

• Air flow measurement
(Velocity mode)
