The SFM4100 is designed to measure air and non-aggressive gases with excellent accuracy over a wide dynamic range. Mass flows of up to 20 slm are available. The SFM4100 series works with a supply voltage of 5 to 9 VDC and can be easily embedded in a microprocessor environment via its digital I2C interface. The robust design of the SFM4100 sensor enables operating pressures of up to 10 barg. The flow signal is internally initialized and temperature compensated. The outstanding performance of these sensors is based on Sensirion's patented CMOSens® sensor technology, which combines sensor element, signal processing and digital calibration on a single microchip. Mass flow is measured by a thermal method on the MEMS sensor element. Compared to other thermal mass flow sensors (MEMS, Hotwire, or capillary type), the SFM4100 features an extended dynamic range, increased long-term stability, and improved repeatability. The proven CMOS technology is perfect for high-quality mass production and is the ideal choice for demanding and cost-sensitive OEM applications. This text is machine translated.
