Siemens® QBM3020-1D Air Duct Differential Pressure Sensor acquires differential, over and under pressure of air and nonaggressive gases if a high degree of measuring accuracy and quality is required. It is also suited for measuring volume flow using differential pressure since the output signal can be set to extracting-the-root.
Fields of Application
- Measuring the slightest differential pressures in air conditioning ducts and ventilation.
- Check air flows.
- Monitor filters and control fans.
- Pressure supervision in labs, production, and clean rooms.
- For acquiring variable airflow in VAV plants on the supply and extract airside.
