DESCRIPTION

The digital PX Series differential pressure transducers utilize highly accurate,
microprocessor profiled sensors and an advanced ceramic capacitive sensing
element. Designed to monitor duct and room pressure in commercial buildings, the

PX Series offers exceptional job-site flexibility. PXP and PXD models feature four

field-selectable ranges. The PXU features seven field-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 configure 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

differential pressure applications

FEATURES

Excellent tolerance to overpressure and vibration reduces field failures

High accuracy digital sensor maintains calibration and reduces callbacks

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

Selectable ranges and scales reduce setup time & number of models

to stock

Microprocessor-based design allows for digitally profiled sensor increasing

product accuracy and reliability

Circuit protection prevents damage due to incorrect wiring

Monitors positive and negative pressure for application versatility

Flexibility: standard and fast response modes
