Abstract:
1. 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 the two shaft sections are configured to rotate with respect to one another, said sensor arrangement comprising: at least one magnetic encoder arranged on the first shaft section; and a stator arranged on the second shaft section, wherein the stator has two stator elements each having projecting fingers, at least one flux concentrator associated with each of the stator elements or jointly associated with the stator elements, the at least one flux concentrator being configured to either directly or indirectly supply to a magnetic field sensor element a magnetic field which is to be detected and is produced by the at least one magnetic encoder, wherein the at least one flux concentrator comprises a ring or ring sector, is arranged in a radial outer area with respect to at least one stator element and is magnetically coupled thereto via an air gap, such that an innermost edge of the at least one flux concentrator is radially outward from an outermost edge of the at least one stator element.
