The SFM3400 sensor series is Sensirion’s digital flow meter designed for neonatal/pediatric medical applications. It measures the flow rate of air, oxygen and other nonaggressive gases with superb 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 SFM3400-AW. Therefore, the SFM3400 series is extremely well suited for proximal flow measurements in neonatal/pediatric medical ventilation and other respiratory applications.
The SFM3400 series has been designed with the 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, best-in-class accuracy and superior robustness to rough handling and adverse conditions.
The well-proven and patented CMOSens® sensor technology is perfectly suited for high-quality mass production and is the ideal choice for demanding and costsensitive OEM applications.
