Abstract
A sensor device includes a base element extending in an axial direction and a first magneto elastic active region representing a first longitudinal section of a surface of the base element. The first longitudinal section extends in the axial direction and is magnetized in a first circumferential direction. The sensor device further comprises a first magnetic field sensor overlapping with the first longitudinal section, and a second magnetic field sensor disposed at a distance with respect to the first magnetic field sensor along the axial direction and overlapping with the first longitudinal section.
