Description

General

The differential pressure sensor acquires differential, over and under pressure of air and non-aggressive 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 monitoring in labs, production, and clean rooms

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