What is an intake air pressure sensor, its composition, working principle, and applications 3

In intake pressure sensors, piezoelectric sensors are usually composed of piezoelectric ceramic plates, metal plates, and support rods. When the gas pressure in the engine intake pipe acts on the piezoelectric ceramic sheet, the ceramic sheet will undergo slight deformation, causing bending deformation of the metal sheet. This bending deformation will change the resistance value of the metal sheet, thereby generating electrical signal output. By amplifying, filtering, and processing this signal, an electrical signal related to the engine intake pressure can be obtained. diode

4、 Application of intake pressure sensor

The intake pressure sensor is a very important sensor, which has a wide range of applications in fields such as automobiles, airplanes, robots, etc.

1. Automotive field

In the automotive field, intake pressure sensors are mainly used in engine control systems. By measuring the pressure in the engine intake pipe, the ECU can adjust parameters such as fuel injection quantity and ignition timing in real time according to different operating conditions, thereby improving the combustion efficiency and power performance of the engine.diode
