There are generally two types of position sensor: inductive and Hall-effect.

• Inductive sensor

  It consists of a solenoid subjected to the action of a permanent magnet. Any movement of a ferromagnetic mass near the magnet creates a variation in the magnetic field to which the solenoid is subjected, generating a voltage proportional to the derivative of the flux with respect to time. This type of sensor is associated with a target...
