SCHMIDT Flow Sensor SS 20.415 for Cleanrooms

The SCHMIDT Flow Sensor SS 20.415 is a highly specialised sensor for laminar-flow monitoring in cleanrooms. The sensor is based on the principle of a thermal anemometer and can measure the flow velocity in two directions and can precisely detect the flow direction. The housing of the sensor is a thin stainless steel pipe measuring only 9 mm in diameter. The complete electronic -based on a microprocessor- is located inside this small pipe. The sensor is robust due to a metal chamber in which the sensing element is protected against impacts. Beneath the analog output this sensor offers two digital outputs to indicate the flow direction and that flow reaches a preselected switching level.

The SS 20.415 comes with the treasured SCHMIDT Cleanroom Quick Mounting System. This is a mounting adaptor made of stainless steel, which is mounted onto a wall or ceiling. After inserting the sensor into this adaptor the sensor gets automatically into the right position in regard to the filter outlet. As there is no separate electronic module, mounting or dismounting can be made within seconds. SCHMIDT offers the mounting adaptors in different versions fitting to all standard cleanroom ceiling systems. The sensors housing is completely tight and can be sterilized during operation with alcohol or hydrogen peroxide. Significant is also the fact, that the sensor starts to measure from a velocity of 0,05 m/s. SCHMIDT operates also a high precision wind tunnel and thus offers a calibration certificate for this sensor which is traceable to national standards.

Applications:
Laminarflow monitoring in cleanrooms of pharmaceutical production, fine chemical production, semiconductor industry, optical industry and nutrition industry. Designed to be directly mounted under filter ceilings, flow boxes and inside of isolators.
