Patent ID: 8087306

Claim:
A sensor arrangement for measuring 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 be rotated relative 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 stator element having protruding fingers, and wherein the stator elements are either respectively or jointly associated with a flux concentrator which conducts a magnetic field to be detected that is generated by the magnetic encoder, either directly or indirectly to at least one magnetic field sensor element, wherein at least one flux concentrator is fixed to a carrier element, wherein at least a portion of the carrier element is composed of an elastic material, wherein each stator element comprises a radially protruding ring and each of the stator elements is associated with a flux concentrator fixed to a carrier element, wherein the carrier element has at least one centering device embodied such that it can at least partially encompass and align the ring of the associated stator element between stator element and carrier element, wherein the at least one carrier element has an expanding recess, into which an expanding element is at least partly inserted, wherein the at least one centering device of the carrier element is at least partially widened by the expanding element.
