Product Introduction
The CAFS1000A Series MEMS air flow sensor, also known as an air
flow meter, is a cutting-edge solution for modern automotive
electronic control fuel injection systems (EFI). Installed between
the air filter and the throttle body, it measures the amount of air
entering the engine. This measurement is crucial as the output
signal serves as a primary parameter for the fuel injection system
in automotive engines, influencing power performance, fuel economy,
and emission control.
The CAFS1000A Series sensors utilize the principle that the heat
from the sensor is dissipated by incoming air—the greater the
airflow, the more heat is dissipated, resulting in a measurable
temperature difference. This allows for accurate data processing
and determination of airflow direction via a peripheral hybrid
processing circuit. By ensuring optimal fuel-air mixture ratios
under varying operating conditions, these sensors play a vital role
in improving energy efficiency and reducing pollutant emissions in
modern vehicles.
With years of application in the automotive and related industries,
the CAFS1000A Series has proven its high reliability, stability,
accuracy, and cost-effectiveness. Its broad application and
promotion potential make it an invaluable component in automotive
air flow measurement.
