air-diff-sensorSiemens pressure sensors for acquiring the differential pressure of air or non-aggressive gases in ventilation, air conditioning and heating plants.

  • pressure linear characteristic with selectable pressure measuring range
  • operating voltage 24Vac/dc
  • 0..10Vdc or 4..20mA output signal

Please note, there are many options available, including other ranges with or without displays.
