DESCRIPTION
The digital PX Series dierential pressure transducers utilize highly accurate,
microprocessor proled sensors and an advanced ceramic capacitive sensing
element. Designed to monitor duct and room pressure in commercial buildings, the
PX Series oers exceptional job-site exibility. PXP and PXD models feature four
eld-selectable ranges. The PXU features seven eld-selectable ranges, allowing just
one model to cover applications for 0-0.1” to 0-10” W.C. The directional mode jumper
is used to congure the transducer in unidirectional or bidirectional mode for room
and building static pressure applications. All models feature a pushbutton and digital
input terminal to zero the output. The microprocessor is programmed to prevent
accidental zero adjustment during normal operation.
APPLICATIONS
● Static pressure in duct or room applications
● Variable air volume system control
● Filter status monitoring
● Clean rooms, hospitals, fume hoods, computer rooms, and other very low
PRESSURE
dierential pressure applications
