Pressure-resistant mass flow meter for gas mixing medtech applications

Sensirions new SFM4200 mass flow meter can be operated at pressures of up to 8 bar and measures flow rates up to 160 slm with a rapid signal processing time of 0.5 ms due to its high pressure resistance. It is particularly suitable for gas mixing in medical applications.

Sensirion is one of the leading manufacturers of innovative sensors. The SFM4200 measures air, oxygen and other non-corrosive gases with an high level of accuracy, and is more pressure-resistant than its predecessors, while delivering reliable and precise measurements. With a signal processing time of 0.5 ms, the sensor is incredibly fast, as well as highly accurate. Its pressure resistance makes it ideally suited to high-volume medical applications such as oxygen gas mixing in respiratory applications, where the sensor is integrated into the high-pressure side. Customers can therefore install the SFM4200 flexibly and use it to develop their own products or to transform the design.

The SFM4200 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 performance of this sensor 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 the gas is measured by a thermal sensor element which assures very fast signal processing time and bidirectional measurement with accuracy. The CMOS Technology is suited for high-quality mass production and can be used for demanding and cost-sensitive customer-specific applications.
