Differential pressure transmitters DPTA HONEYWELL / FEMA are suitable for:

  • air-conditioning and environmental protection
  • valve and flap control in building automation
  • filter and blower monitoring
  • fluid and level monitoring.

The DPTAQ multi-range model features eight selectable measurement ranges set using the adjustment dial and offers the advantages of long-term stability due to automatic offset calibration. One model is suitable for measuring extremely small pressures (0…25 Pa / 0…50 Pa).

FEATURES:

  • Monitoring gaseous media
  • Piezo-resistive pressure transducer
  • Up to 20 kPa overload capacity
  • Easy installation and wiring connection
  • DPTAQ8 with eight measuring ranges and test adjustment 0 V / 10 V / 4 mA / 20 mA
  • DPTA25 with extremely small measurement range
  • Response time adjustable by jumper
  • Output signal adjustable by jumper
  • Automatic offset recalibration

NOTE: These sensors are not suitable for use in installations under periodic inspection by the U.S. Food and Drug Administration.
