Siemens QBM3230U2D : Differential Pressure Transmitter, Field Selectable Pressure Range 0" to 2", Selectable Range/Output, Display, Field Selectable Outputs: 4-20 mA, 0-5 VDC, or 0-10 VDC, LCD Display, Pushbutton Zero Function, 5-Year Warranty
The sensor acquires differential pressure, overpressure and negative pressure of air and non-aggressive gases when a high degree of measuring accuracy and quality is required. It is also suited for measuring air volume flow via differential pressure, since the output signal can be set to extracting-the-root.
The differential pressure sensor is used for:
- Measuring the differential pressures in ventilation and air conditioning ducts
- Verifying air volume flow
- Monitoring filters and control fans
- Pressure supervision in labs, production, and clean rooms
- Acquiring variable air flow in VAV systems
