Beschreibung
Zusammenfassung:	A sensor device comprises at least one test magnet which is designed to provide a magnetic test field, a first sensor element which is designed to capture a magnetic field and to provide a first sensor signal, wherein the first sensor signal comprises a first signal contribution on the basis of the magnetic test field, a second sensor element which is designed to capture a magnetic field and to provide a second sensor signal, wherein the second sensor signal comprises a second signal contribution on the basis of the magnetic test field, wherein the magnetic test field at the location of the first sensor element differs from the magnetic test field at the location of the second sensor element.
