SIEMENS Differential pressure sensor QBM3120-25 24VDC 4-20mA 0 to +2500Pa without display
Differential pressure sensor for sensing the pressure difference, overpressure and underpressure of air and non-aggressive gases where high accuracy and measurement quality are required. It is also suitable for volumetric flow measurement using a pressure difference, as the output signal can be set to a square root characteristic.
  • High measurement accuracy
  • Adjustable measuring characteristic (linear or square root)
  • Operating voltage: QBM3020-..: AC 24 V / DC 13.5...33 V / QBM3120-..: DC 8...33 V
  • Output signal: QBM3020-..: DC 0...10 V / QBM3120-..: 4...20 mA
  • Setting the zero point
  • Simple and quick installation using mounting brackets integrated into the sensor housing
  • Maintenance-free due to excellent long-term stability
  • Calibrated and temperature compensated measurement signal
  • A plastic tube is included in the delivery
  • Very short response time
  • Displaying the current value depending on the type

Fields of application
  • Measurement of minimum pressure differences in ventilation and air conditioning pipes
  • Air flow control
  • Filter condition monitoring and fan control
  • Pressure monitoring in laboratories, production zones and in clean environment operations
  • Measurement of supply and exhaust air flow in VAV systems (with variable air flow)
