Rapid Response Time High Accuracy MEMS Air Flow Sensor

Product Introduction

The CAFS1000A series MEMS air flow sensor (i.e. air flow meter) is applied in modern electronic fuel injection systems (EFI) of automobiles. It is generally installed on the intake duct between the air filter and throttle body to measure the amount of air sucked into the engine. Its output signal serves as the main parameter for controlling fuel injection in the fuel injection system of automotive engines, determining the engine's power, economy, and emission performance indicators. In order for an electronic fuel injection engine to obtain a mixture of fuel concentration under various operating conditions, it is necessary to accurately measure the amount of air sucked into the engine at each moment, as the main basis for the electronic control unit to calculate and control the fuel injection amount. Therefore, automotive air flow sensors play an extremely important role in saving energy consumption and controlling pollutant emissions in modern cars.
The CAFS1000A series products have been validated in the automotive and related industries for many years, and can meet the high reliability, high stability, high precision, and low cost requirements of automotive grade use. The promotion of product applications will be very broad.
