Sensirion SFM3304-D Digital Disposable Mass Flow Meter
Sensirion SFM3304-D Digital Disposable Mass Flow Meter is a digital flow meter with particularly small dead space designed for proximal applications. It measures the flow of air and other non-aggressive gases from -250slm to +250slm. The SFM3304-D is a single-use disposable sensor with medical cones for pneumatic connection to standard breathing circuits and an easy-to-use and reliable electrical connector. 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.
Based on the SFM3300-250-D, the SFM3304-D offers improved specifications and additional features due to a newer chip generation, including tunable response time, noise level, and sampling rate. The SFM3304-D is offered in individual packaging. Standard individual packaging is available for the SFM3304-250-D-(x) orderable variants. Customer-specific label versions can be created upon request.
The Sensirion SFM3304-D is an electronic component intended for integration into customer systems. It is not certified as a medical device and is not intended for direct use without integration into and validation within a complete system.
