The SFM3200 sensor is Sensirion’s digital flow meter designed for high-volume applications. The SFM3200 measures the flow rate of air, oxygen and other nonaggressive gases with superb accuracy. A special design of the flow channel results in the very low pressure drop through the flow body of the sensor making it extremely suitable for things like medical ventilation and respiratory applications. The SFM3200 is designed to be resilient to rough handling and performs reliably at variable inlet conditions. The outstanding performance of these sensors is based on Sensirion’s patented CMOSens^® sensor technology, which combines the sensor element, signal processing and digital calibration on a single microchip. The flow rate of a gas is measured by a thermal sensor element which assures very fast signal processing time and bidirectional measurement mode with best in class accuracy. The signal is internally linearized and temperature compensated.
