Single-Use Flow Sensor SFM3300-D for Proximal Flow Measurement
The SFM3300-D flow sensor is a single-use sensor for proximal flow measurement in respiratory applications such as ventilation or anesthesia.
It features outstanding measuring accuracy and robustness as well as a short signal processing time. The digital flow sensor measures bidirectional flow volumes of up to 250 slm and is fully calibrated for air, N2 and O2 gases. The special design of the flow channel results in a low dead space volume and the slightly greater pressure drop ensures more stability compared to variable inlet conditions. The sensor also features medical cones for pneumatic connection to the respiratory cycle and has a mechanical interface for a user-friendly electrical connection. Thanks to its performance characteristics, the SDM3300-D mass flow meter is ideally suited for single-use proximal flow measurements in medical ventilation, hospital applications, residential care applications and emergency situations.
Like all Sensirion sensors, the SFM3300-D is based on the innovative CMOSens® Technology, which combines the sensor element and processing electronics on a single, tiny CMOS microchip. The CMOSens® mass flow sensor offers durably stable and interference-free measurement and enables a very fast and highly precise sensor signal.
