Particularly suitable for gas mixing in medical applications, the SF4200 measures air, oxygen and other non-corrosive gases with high accuracy. It operates from a 5 Volt supply voltage and features a digital two-wire I2C interface. The measurement results are internally linearized and temperature compensated. The unit is built around Sensirion’s patented CMOSens sensor technology, which combines the sensor element, signal processing and digital calibration on a single microchip. The flow rate of the gas is measured by a thermal sensor element which assures very fast signal processing time and bidirectional measurement with best-in-class accuracy.
