Inductive sensors are used for speed sensing and are based on the principle of electric voltage induction in the coil caused by magnetic field change.
These sensors are used for speed and position sensing of the ferromagnetic target wheel or of a mark from magnetically soft material.
The measurement variable of the inductive sensors is output voltage, which is further processed in the control unit.
Inductive sensors are considered as one of the most reliable options and are suitable for a broad range of applications, e.g. pulse sensors.
