An ICP (Integrated Circuit Piezoelectric) sensor is a type of sensor that converts pressure into an electrical signal. It is commonly used in automotive and industrial applications to measure pressure in various systems, such as engines, transmissions, and hydraulic systems.

ICP sensors are constructed with a piezoelectric element, which generates an electrical charge when subjected to mechanical stress. This charge is then converted into a voltage signal by an integrated circuit (IC) amplifier. The output voltage signal is proportional to the pressure applied to the sensor.

Diagram of an ICP Sensor

A typical ICP sensor consists of the following components:

  • Piezoelectric element: Converts pressure into an electrical charge.
  • IC amplifier: Amplifies and converts the electrical charge into a voltage signal.
  • Housing: Protects the sensor from environmental factors.
  • Electrical connector: Provides a connection to the measurement system.
