The digital PX Series differential pressure transducers utilize highly accurate, microprocessor profiled sensors. Designed to monitor duct and room pressure in commercial buildings, the PX Series offers exceptional job-site flexibility, with four field-selectable range options. 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. PX Series pressure transducers utilize an advanced ceramic capacitive sensing element that provides a highly stable linear output, reducing offset errors. APPLICATIONS   Static pressure in duct or room applications Variable air volume system control Filter status monitoring Exceptional accuracy and stability   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 Lowest total installed cost   Switch-selectable ranges and scales reduce setup time and number of models to stock Microprocessor-based design allows for digitally profiled sensor increasing product accuracy and reliability Brass barb fittings prevent breakage and accomodate popular tubing sizes Low-differential room pressure sensor with LCD display   Ideal for clean rooms, hospitals, fume hoods, computer rooms, and other very low differential pressure applications Monitors positive and negative pressure for application versatility Flexibility: standard and fast response modes
