SFM3505-300-X
SensirionSFM3505-300-X is the high-accuracy version of Sensirion's SFM3505 mass flow meter module for inspiratory gas flow in ventilators and anesthesia equipment, measuring -150 to +300 slm at 1.5% of measured value accuracy, with digital I2C output, fifth-generation CMOSens sensing, on-chip temperature compensation and air/O2 calibration (Sensirion material number 3.001.273). Selection advice: choose the -X code when the flow metering budget matters - ventilator tidal-volume accuracy is the typical driver - and the standard SFM3505-300 (2.3%) when it does not; both share the same mechanical and interface design, so the accuracy tier can be switched on the same board. Sensirion's datasheet ordering table prints this exact code, its July 2026 release announced general availability, and the catalog lists the -X as New. Parameters verified against Sensirion documentation.
