Sensirion SFM3300: proximal medical flow sensor, ±250 slm bidirectional, calibrated for air and O₂, I²C output (AW / D versions).
SFM3300 is a digital mass flow sensor developed by Sensirion for proximal flow measurement in respiratory devices. It measures bidirectional flow up to ±250 slm and is fully calibrated for air and O₂. It comes in two versions, the autoclavable / washable SFM3300-AW and the single-use SFM3300-D. Its standard medical cone connectors and low dead space make it suitable for ventilation and anaesthesia applications.
