Honeywell’s P7650 sensor can measure either air pressure or velocity. It is available in duct mount, panel mount or universal mount configurations. Duct and panel models have two pressure and velocity options with four field-selectable sub-ranges. The universal model comes in one pressure/velocity range with seven field selectable sub-ranges. All variants are available with and without display. The P7650 has an IP65/NEMA 4 environmental rating.


  • Excellent tolerance to overpressure and vibration reduces field failures
  • Selectable ranges and scales reduce setup time and number of models to stock
  • High accuracy digital sensor with seven selectable sub-ranges maintains calibration and reduces callbacks
  • IP65/NEMA 4 housing allows for mounting in wash-down locations
  • High reliability sensor technology for long-term, maintenance-free operation
  • Circuit protection avoids damage due to incorrect input wiring

Product Specifications

Sensors measure static and differential air pressure in duct and panel applications and can measure air velocity using pressure-velocity pick up tubes.
