Delta P: air pressure delta

Delta P: air pressure delta

Monitor the operation of a ventilation box, air handling unit or building air system
  • Pressure difference: relative to the atmospheric pressure or between two different zones
  • 2 digital inputs / outputs:  for connecting to a PLC for tracing alerts or operating states
  • 1 analogue input 0-10V: for connecting to a sensor
  • Compatible with KARE and KARE+ services
  • Available in: Smart Delta P version
Example of use case


The DELTA P IoT sensor is part of the IAMo solution. 

A complete offer dedicated to the monitoring and analysis of Indoor Air Quality, comfort and ventilation in your buildings



Measure a delta pressure:

  • Between the atmospheric pressure and the inside of the ventilation box

  • On both sides of an element (e.g.: filter)

Collect data of a 0-10V sensor

e.g. ammeter clamp for distinguishing a power failure


Controlling the AON outputs



On exceeding threshold(s)

Pressure difference or through 0-10V input

On digital input events

e.g.: indication of a machine fault
