Pressure - Low DP 0-2"

  • Product improvement is a continual process at Senva
  • This product is being at end of life 
  • The new P4, P5, and P6 series are upgrades
  • Please contact Senva for any account transition needs


  • Ideal for clean rooms, hospitals, fume hoods, computer rooms, and other very low differential pressure applications
  • Static pressure in duct or room, variable air volume system control, and filter status monitoring


This PDP3X-002-A series dry media pressure sensors cover up to 0-2” (0-500Pa) and offers industry-leading long-term stability thanks to a fully calibrated and temperature compensated application specific integrated circuit (ASIC) in the piezoresistive silicon pressure sensor. The sensor features five field selectable ranges in both inches of WC and pascals, dual 0-5/0-10VDC and 4-20mA outputs, uni/bi-directional modes, and LCD readout for ease of installation.
