Application

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
