Siemens QBM2030 1U Differential Pressure Sensor

KSh 19127

Siemens QBM2030 1U Differential Pressure Sensor is used to measure the slightest differential pressures variation in ventilation and air conditioning ducts, also Monitoring filters and control fans with output available in the device. The siemens pressure sensor acquires differential, over and under the pressure of air and nonaggressive gases.
Applications: HVAC applications, cooling channels, Pharmaceutical Clean Rooms, and AHU applications Check wind streams, Monitor channels, and control fans


Siemens QBM2030-1U Differential Pressure Sensor acquires the differential pressure using a silicon rubber membrane and ceramic lever. The sensor generates a linear and temperature-compensated output signal DC 0 to 10 V, as per the deflection.
Features of Siemens Differential Pressure Sensor:

  • Pressure-linear characteristic with selectable pressure measuring range
  • Operating voltage AC 24 V or DC 13.5…33 V
  • Output signal DC 0…10 V
  • Zero-point adjustment
  • Simple and fast mounting thanks to integrated mounting brackets in the housing
  • Maintenance-free
  • Calibrated and temperature-compensated measuring signal
  • Supplied with tubing connection set
