What is an intake air pressure sensor, its composition, working principle, and applications 1

1. Overview of the Intake Air Pressure Sensor

The intake air pressure sensor is a device used to measure the pressure in the engine's intake manifold. It functions as a sensor capable of converting pressure signals into electrical signals, transforming variations in the intake manifold pressure into electrical outputs that are then transmitted to the ECU (Electronic Control Unit) for processing. This allows the ECU to obtain real-time information about the engine's intake conditions, enabling precise control and optimization of the engine's  diode performance.diode

II. Composition of the Intake Air Pressure Sensor

The main components of the intake pressure sensor include: a pressure-sensitive element, a signal conversion circuit, and terminal blocks.

1. Pressure-sensitive element  diode

The pressure-sensitive element is the core component of the intake air pressure sensor. It is a device capable of directly measuring the pressure in the intake pipe. Common pressure-sensitive elements include piezoelectric sensors such as the EPM570T100C5N, miniature pressure sensors, and piezoresistive sensors.diode
