DIFFERENTIAL PRESSURE SENSOR QBM3020-10

Product Description

The Siemens QBM3020-10 is a high-precision HVAC differential pressure sensor designed to measure very small pressure differences in air ducts and ventilation systems. It is used in building automation systems (BMS) for monitoring airflow, filter status, and room pressure control.

Key Features

• Measures low differential air pressure in HVAC ducts
• High-accuracy diaphragm sensing element
• 0–10V analog output for direct controller input
• Suitable for air and non-aggressive gases
• Zero-point calibration and stable long-term accuracy
• Selectable linear or square-root output (variant dependent)
• Maintenance-free operation
• Compact and easy duct/panel mounting design
• Temperature-compensated measurement signal
• Industrial-grade reliability for building automation systems
