The SFM3300 series is Sensirion’s digital flow meter series designed for medical applications. It measures the flow rate of air, oxygen and other non-aggressive gases with superb accuracy. The special design of the flow channel results in a very small dead space.
The SFM3300 series has been designed with the use by medical professionals in mind. It features medical cones for pneumatic connection to standard breathing circuits and a mechanical interface for easy and reliable electrical reconnection. The sensor element, signal processing and digital calibration are on a single microchip assuring very fast signal processing time, best-in-class accuracy and superior robustness to rough handling and adverse conditions. The well-proven and patented CMOSens sensor technology is perfectly suited for high-quality mass production and is the ideal choice for demanding and costsensitive OEM applications.
The SFM3300 series flow meter features a fifth-generation silicon sensor chip. In addition to a thermal mass flow sensor element, the chip contains an amplifier, A/D converter, EEPROM memory, digital signal processing circuitry, and interface. Due to seamless integration of signal acquisition and processing on the single silicon die significant performance and cost benefits are achieved.
