Value Dry Pressure (0-0.25 to 25")

  • Range and output specific models  from 0-0.1 to 0-25”
  • 0-5, 0-10VDC, 4-20mA  loop powered  or three wire 4-20 mA versions
  • Optional pressure probe adapts for duct or remote mounting
  • Non-position sensitive for easy placement
  • DIN mountable--compact for panel space conservation
  • Zero push button and contact closure


  • Building (zone) pressure
  • Filter condition measurement
  • Duct/static
  • OEM HVAC equipment


The P4 dry media pressure transmitter features fixed ranges optimized for building (zone) pressure, filter measurement, and static duct applications. Innovative static probe integrates with unit or can be mouted remotely for static or filter pressure with additional probe.

Model Range Output Directional Accuracy Display Duct Probe?
  • Time and space saving installation for field and OEM applications
  • 0-5VDC/10VDC 4-20 mA loopand 4-20mA 3 wire output options
  • Address duct, filter, and remote probe mounting with a single unit  
  • Remote probe mounting accepts both 1/4” and 3/8” ID hose
  • Non-position sensitive for easy placement
  • DIN mount - forward for LCD panel applications Side DIN mount to maximize panel space
  • Conduit cover for 3/8” flex connectors
  • LED for status indication and location in ductwork LED: Power heartbeat, ,momentary rapid flash = auto-zero complete, continual rapid flash = 110% over pressure
  • LED facilitates locating sensor in ductwork
