AFM3020 Air Flow Sensor


SKU: AFM3020 Air Flow Sensor Categories: ,


AFM3020 Air Flow Sensor Introduction:

A digital flow meter made by Aosong specifically for ventilator applications is the AFM3020 sensor. It accurately determines the flow rate of non-aggressive gases like oxygen, air, and other. Due to a unique flow channel design, the sensor has a very minimal pressure drop through its flow body, making it ideal for use in demanding applications like respiratory and medical ventilation. The AFM3020 has a digital I2C interface and runs on a 5 Volt supply source. After inner calibration and temperature adjustment, the measured value is output. It integrates a 24-bit AD acquisition CMOS CPU with a high-performance thermal sensor device. The thermal sensor chip detects gas flow, ensuring extremely quick signal processing and more accuracy than comparable technologies.
