The A/DP2 and A/LP2 Differential Pressure Sensors have been phased-out and replaced. The ACI Design Team worked hard to replace these products with a new series including even more features. 

 The new product series is the A/DLP and it features:

  • New enclosure with hinged cover for easy access
  • Improved accuracies (± 0.50% or ± 0.25% FSO)
  • Pitot tube and DIN rail clip accessories
  • Field selectable ranges and outputs
  • Pushbutton zero function
  • Spring-loaded terminals
  • Ranges up to 40” w.c.
  • A larger LCD display


The new A/DLP Series is AVAILABLE NOW and the A/DP2 and A/LP2 Series are no longer available. Going forward warranty replacements for the A/LP2 or A/DP2 Series will be fulfilled by the A/DLP Series.
