What is an intake air pressure sensor, its composition, working principle, and applications 2

2. Signal Conversion Circuit

The signal conversion circuit is a crucial component that transforms pressure signals measured by the pressure-sensitive element into electrical signals. It typically consists of operational amplifiers, resistors, capacitors, and other elements. In the conversion circuit, the operational amplifier serves to amplify and filter the signals, while resistors and capacitors are used to adjust the circuit's impedance and frequency response.diode

3. Terminal block

The terminal is the connecting part between the intake pressure sensor and other electronic components. It is typically made of metal materials, featuring certain heat and corrosion resistance, high reliability, and the ability to stably transmit signals to other electronic components.diode

3. Working Principle of the Intake Air Pressure Sensor

The working principle of the intake air pressure sensor is based on physical principles such as the piezoelectric effect, resistance effect, or capacitive effect. Among these, the piezoelectric sensor is the most common type, and its operation relies on the piezoelectric effect.diode

The piezoelectric effect refers to the phenomenon in certain crystalline materials where an uneven distribution of charges occurs when external pressure is applied, resulting in an electric potential difference. By utilizing this effect, piezoelectric sensors can convert measured pressure signals into electrical signals diode
