Eddy current-based angle sensor

摘要

The invention relates to an inductive angle sensor that includes a measuring element able to be positioned, within an angle measurement range, in different angle-positions about a rotational axis, as well as a coil that is at a distance from said measuring element. The surface of the measuring element is at a different distance from the coil in each angle-position, within said angle measurement range.
