PX3 Series
Differential Pressure / Air Velocity Transducer
Product Overview
The PX3 transducer can measure either air pressure or velocity with the ip of a switc h.
The PX3 is available in three installation congurations: duc t, panel or universal. D uct and
panel models have two pressure and velocit y options: 0-1” WC / 0-3,000 ft/min or
1-10” WC / 3,000- 6,000 ft/min with f our eld-selectable sub-ranges. The universal
model comes in one pressure/velocit y range: 0-10” WC / 0-7,000 ft/min with seven
eld-sele ctable 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.

8. Wait ve seconds, then press and hold the ZERO pushbutton for two
seconds or provide contac t closure on the AUX ZERO terminal. This will reset
the output and display to zero pressure. For bes t accuracy, press the ZERO
button while both por ts are open to atmospheric pressure. To protec t the unit
from accidental zero, this feature is enabled only when the detected pressure
is within about 0.1 in. WC (25 Pa) of factory calib ration.
9. Connect desired external tubing to the PX3.

PX3 Series devices employ ceramic capacitive sensor s and sophisticated
temperature compensation circuitry. The sensor achieves its best accuracy af ter
an initial warm-up period. During the rst few minutes of operation, readings
at zero pressure and the lowest pressure ranges appear erroneous. Following
this initial warm-up period, the PX3 device maintains it s specied accurac y and
st abili ty.
The LCD momentarily indicates range ‘SET’ when a selection is made. Pressure
is normally indicated on the display. Units are in inches water column (in. WC),
Pascals (Pa) or kilopascals (kPa) as indicated on the display. The display shows
‘OVER’ when the pressure is over range.
