Cleanroom Flow Sensor: Laminar Flow Security in perfection and GMP-compliant design! Perfect for validation of laminar flow in applications with frequent cleaning intervals or product changes.

Flow monitoring in cleanrooms and clean zones

A direction-defined airflow in cleanrooms protects the products against contamination and unwanted particles will be safely evacuated. To do so, a uniform air flow from the ceiling to the floor (“oriented, low-turbulence displacement flow“) is maintained in cleanrooms of high purity levels. The monitoring range is from w_N = 0.36 to 0.54 m/s flow velocity. In the cleanroom, the measurements are made behind terminal filters. Since the recirculation of air is reduced during standstill periods, an extremely precise measurement of the air velocity is mandatory from 0.1 m/s onwards.

Air flow measurement and control by SCHMIDT^® Flow Sensor SS 20.715 LED

The thermal SCHMIDT^® Flow Sensor SS 20.715 LED is the robust solution for extremely challenging cleanroom applications. Product changes in pharmaceutical filling systems or internal requirements force operators of cleanrooms and systems in clean zones to clean them regularly. When aggresive media is used for cleaning or more intensive cleaning is required due to considerable or very stubborn contamination, the new SS 20.715 LED laminar flow sensor with double-pin sensor head made of stainless steel is the first choice. The double-pin sensor head has been designed to meet the aforementioned requirements and, due to the sensor elements being completely encapsulated in stainless steel these are ideally suited for extremely demanding applications. In addition to the flow velocity, the SS 20.715 LED also measures the process temperature, with a range of -20 to +70 °C.

Thanks to the SCHMIDT^® cleanroom-compliant quick assembly kit, the flow sensor can be installed easily or even exchanged for an existing sensor without any additional effort.

On request the SS 20.715 LED can also be delivered with a DAkkS accredited calibration.
