Abstract
A sensor arrangement for measurement of a torque acting on a shaft, wherein the shaft has a first shaft section and a second shaft section and these two shaft sections can rotate with respect to one another, having at least one magnetic encoder which is arranged on the first shaft section and having a stator which is arranged on the second shaft section, wherein the stator has two stator elements each having projecting fingers, and a flux concentrator is associated with each of the stator elements and directly or indirectly supplies to a magnetic field sensor element the magnetic field which is to be detected and is produced by the magnetic encoder, wherein the at least one flux concentrator includes a ring or ring sector, is arranged essentially in the radial outer area with respect to at least one stator element and is magnetically coupled thereto via an air gap.
