Product, process, and personnel safety in cleanrooms and cleanroom-like environments is usually ensured by maintaining defined, cascade-overpressure rooms. This creates an airflow from areas with higher cleanliness to areas with lower cleanliness (except for negative pressure rooms with opposing req…

The measurement of laminar airflow velocities in cleanrooms places the highest demands on the sensors. Choosing a suitable measurement method for accurately detecting even the smallest flow velocities is only the first hurdle. Design aspects such as an easy-to-clean, wear- and drift-free constructio…

SCHMIDT® Flow Sensors SS 20.400 and their ATEX counterpart SS 23.400 detect even the smallest airflows from 0.05 m/s. They also feature integrated direction detection. In addition to pressure measurement, the bidirectional flow sensors can reliably detect existing overflows in cleanrooms or control…

In many industrial processes, air or gases of various kinds are used. Volume and mass flows, flow velocities, or flow directions must be reliably and often precisely measured. SCHMIDT® flow sensors, based on the principle of thermal anemometry, do this even under the most challenging conditions.
