Abstract
A sensor device for measuring a rotational position of an element that is rotatable about an axis of rotation includes a sender member emitting a magnetic field, a first receiving member formed by a first conductor and receiving the magnetic field, and a second receiving member formed by a second conductor and receiving the magnetic field. The first receiving member and the second receiving member are arranged within an annular ring segment having a period along a circumferential direction about the axis of rotation. The first conductor and the second conductor each define a plurality of loops. A shape of each of the loops follows in the circumferential direction a base function with half the period, the shape of only some of the loops deviates from the base function by a correction function.
