Sensirion: sensitive gas mixture measurements at low flow rates
Sensirion will present the brand new mass flow meter SFM4300 at this year’s Compamed in Düsseldorf. Thanks to its newly developed flow channel geometry, the sensor is able to precisely measure oxygen and laughing gas in addition to air for the first time. The small sensor is thus excellently suited to the measurement of gas mixtures in the medtech sector.
Compared to its predecessor, the SFM4100, the SFM4300 features improved sensitivity and is extremely precise when measuring mass flow, even at low flow rates. The SFM4300 is small and very pressure-resistant, measures mass flows of up to 20 slm (air, O2 and N2O) and is available with various mechanical connections (downmount, Legris and O-rings). The sensor unit, which was developed for integration into anesthesia devices among other applications, has an I²C interface and provides a fully calibrated and temperature-compensated output signal.
