Use
The 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 via differential pressure since the output signal can be set to extracting-the-root.
Fields of application
• Measuring the slightest differential pressures in ventilation and air conditioning ducts
• Check air flows
• Monitor filters and control fans
• Pressure supervision in labs, production, and clean rooms
• For acquiring variable air flow in VAV plants on the supply and extract air side
