SENSIRION SFM3003-300-CET FLOW SENSOR, -150TO 300LPM, -20TO85DEG C

SFM3003-300-CET is a versatile, low-pressure drop, bidirectional flow meter. Compared to the SFM3019, the SFM3003 comes with a wider flow range as well as improved specifications. The SFM3003 outputs an easily integrable digital I2C interface. The outstanding performance of the SFM3003 sensor is based on Sensirion�s patented CMOSens® Technology, which combines the sensor element, signal processing and digital calibration on a tiny microchip. Gas is measured by a thermal sensor element to provide an extended dynamic range and enhanced long-term stability compared to other flow-measuring technologies. The SFM3003 series is the ideal choice for medical and industrial applications.
