General

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 as well as a requirement for a calibration certificate.

Fields of application:

• Measuring slightest differential pressures in ventilation and air conditioning ducts

• Check air flows

• Monitor filters and control fans

• Pressure supervision in labs, production, storage and clean rooms

• For acquiring variable air flow in VAV plants on the supply and extract air side
