How Many Types of Automotive Air Flow Sensors Are There?
1 Answers
Automotive air flow sensors can be categorized into the following types: flap-type air flow sensors, Karman vortex air flow sensors, and temperature-pressure compensated air flow sensors. Below is an introduction to these sensors: 1. Flap-type air flow sensor: Installed between the air filter and the throttle in gasoline engines, its function is to detect the engine's intake air volume, convert the detection results into electrical signals, and then input them into the microcomputer. This sensor consists of two parts: an air flow meter and a potentiometer. 2. Karman vortex air flow sensor: To overcome the shortcomings of the flap-type air flow sensor—such as expanding the measurement range while ensuring measurement accuracy and eliminating sliding contacts—a compact and lightweight air flow sensor was developed, known as the Karman vortex air flow sensor.
