SIEMENS Differential pressure sensor QBM3120-3 24VDC 4-20mA 0 to +300Pa 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)
