Digital flow meter for medical applications
14 November 2018, Analogue, Mixed Signal, LSI

The SFM3400 sensor series is Sensirion’s digital flow meter designed for neonatal/paediatric medical applications. It measures the flow rate of air, oxygen and other non-aggressive gases with high accuracy. The special design of the flow channel results in a very small dead space.

The SFM3400-AW is designed for multiple use, with the ability to withstand autoclave procedures. The single-use version SFM3400-D is in development stage with preliminary specifications identical to the SFM3400-AW. Therefore, the SFM3400 series is well suited for proximal flow measurements in neonatal/paediatric medical ventilation and other respiratory applications.

The SFM3400 series has been designed with use by medical professionals in mind. It features medical cones for pneumatic connection to standard breathing circuits and a mechanical interface for easy and reliable electrical reconnection. The sensor element, signal processing and digital calibration are on a single microchip, assuring very fast signal processing time, high accuracy and robustness to rough handling and adverse conditions.

The patented CMOSens sensor technology is well suited for high-quality mass production and for demanding and cost-sensitive OEM applications.
