Thanks to its newly developed flow channel geometry, the sensor is able to measure oxygen (O₂) and laughing gas (N₂O) in addition to air for the first time. The small sensor is thus suited to the measurement of gas mixtures in the medtech sector. The SFM4300 has improved sensitivity and is precise when measuring mass flow, even at low flow rates. The SFM4300 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. “The SFM4300's performance characteristics make it the ideal solution for controlling gas mixtures in the medtech sector. It enables the mixing of very precise concentrations even at low flow rates,” says the leading product manager, Dr. Daniel Träutlein. According to Träutlein, the sensor will primarily be used in anesthesia devices and is usually integrated directly into the device.
