          Autoclavable
          Flow Meters for Medical Applications

          
Sensirion's new
          SFM3200-AW and SFM3300-AW mass flow meters are autoclavable,
          meaning they can be sterilized and reused. Comprehensive tests
          with outstanding results have verified that the sensors remain
          fully functional after repeated wash and autoclaving cycles.

          
The SFM3200-AW
          and SFM3300-AW mass flow meters are particularly well-suited
          to expiratory or proximal flow measurements and flow measurements
          for drug delivery. They offer high-precision flow measurements
          of air, oxygen and other non-aggressive gases. The SFM3200-AW
          is designed for an extremely low pressure drop in the sensor
          element, making the flow meter especially well-suited to expiratory
          flow measurements in medical applications. The sensor boasts
          high precision at very low flow rates and also at rates up to
          250 slm. It offers a very fast signal processing time and robustness
          to rough handling and adverse conditions.



          The SFM3300-AW is entirely bidirectional, with the capacity to
          measure flows of up to 250 slm in both directions. It is particularly
          well-suited to measuring proximal flow in medical ventilation
          and other respiratory applications since the dead space with
          respect to the pressure drop has been kept to a minimum. The
          somewhat greater pressure drop compared to the SFM3200-AW offers
          greater stability for varying inlet conditions such as those
          occurring with the proximal measurement. Both sensors can be
          connected via medical cones for the pneumatic connection to the
          breathing cycle and have a mechanical interface for a user-friendly
          electrical connection.

          
Like all Sensirion
          sensors, the SFM3200-AW and SFM3300-AW are based on the patented
          CMOSens® Technology, which enables the integration of sensor
          and signal processing circuitry on a single tiny CMOS silicon
          chip. The result is an ultra-precision system that offers long-term
          stability for sophisticated and cost-sensitive applications.
          The technology can also withstand considerable environmental
          effects, which is why CMOSens® based flow sensors are perfect
          for use as sterilizable sensors.
