Product Introduction
Gas Flow Sensor AFM3000 Series Description:
The AFM3000 series sensor is a gas flow meter from Aosong Electronics, designed specifically for ventilator applications. It measures the flow of air, oxygen, and other non-aggressive gases with high precision. The special design of the flow channel results in a very low pressure drop across the sensor, making its performance suitable for various demanding applications such as medical ventilation and respiratory applications.
The AFM3000 operates on a 5V supply voltage and features a digital I2C interface. The output measurement results are internally signal-calibrated and temperature-compensated. The outstanding performance of this sensor is based on Aosong Electronics' sensor technology, where gas flow is measured by thermal sensor elements, ensuring very fast signal processing time while providing bidirectional measurement with best-in-class accuracy.
With 17 years of sensor R&D expertise, Aosong Electronics' proven flow products are trusted by customers and are ideal for demanding and cost-sensitive OEM applications.
