Digital analog air flow bidirectional measurement sensor

Product Overview

The AFM3000 is a digital flow meter sensor specifically designed for ventilators. It provides highly accurate measurements of the flow of air, oxygen, and other non-corrosive gases. Featuring a specially designed airflow duct within the sensor, the AFM3000 ensures minimal pressure loss in the airflow. This makes it ideal for applications requiring precise flow measurements, such as in medical ventilators.

Using a 5V supply voltage, the AFM3000 outputs measurements using a digital I2C interface. Measurements are internally calibrated and temperature compensated. The sensor is internally connected to a thermal chip and a high-performance 24-bit CMOS microprocessor. The gas flow is measured by the thermal sensor, resulting in a very fast signal processing time and the highest measurement accuracy compared to similar products.
