Introducing the SCHMIDT® Flow Sensor SS 20.715 LED, a robust solution for continuous monitoring of laminar airflow in clean rooms and clean applications. With sensor elements completely encapsulated in stainless steel, it impresses with its resistance to aggressive media and dirt and also offers very good protection during the rough cleaning of pharmaceutical systems.
Monitoring the flow in cleanrooms and clean areas
A direction-defined air flow in clean rooms protects products from contamination and disruptive particles are safely removed. For this purpose, a uniform air flow from the ceiling to the floor is maintained in clean rooms with high cleanliness classes (“directed, low-turbulence displacement flow”; monitoring range from wN = 0.36 to 0.54 m/s). The measurement is carried out on the clean room side after the terminal filters. Since the air circulation is throttled during idle times, high-precision measurement of the air speed from 0.1 m/s is necessary.
The solution: measuring the supply air flow with the SCHMIDT® flow sensor SS 20.715 LED
According to the EN ISO 14644-3 standard, the air speed is measured at a distance of around 150 to 300 mm below the front surface of the filter. For easy installation in ceiling and wall systems, the thermal SCHMIDT® flow sensor SS 20.715 LED offers a cleanroom-compatible quick mounting system. The sensor is extremely compact, as all the electronics are built into the sensor tube and therefore no turbulence is generated in the low-turbulence displacement flow.
