Claim Text:
1. A measurement arrangement for a shaft which is mounted in a bearing having a first surface with a raceway formed therein and an end side, which is perpendicular to the first surface, the measurement arrangement comprising: a magnetic coding, the magnetic coding further arranged to exhibit a magnetic field that changes by a magnetostrictive effect in response to a mechanical load applied to the shaft; a cover, which axially closes the bearing, having an outer surface facing away from the magnetic coding and an inner surface facing the magnetic coding; and, a receiver extending along an entire radial length of the inner surface of the cover and continuously contacting the inner surface of the cover, the receiver being operative to detect a change in the magnetic field of the magnetic coding caused by the mechanical load applied to the shaft and the receiver sensing the change in the magnetic field that is produced by the magnetostrictive effect as a result of the mechanical load, wherein the magnetic coding comprises at least one resonant circuit as a signal transmitter for the receiver, and the receiver detects a magnetic component of electromagnetic radiation emitted from the at least one resonant circuit; and, wherein the magnetic coding and the resonant circuit are arranged on the end side of the bearing.
