ABSTRACT:
A measuring arrangement for contactless determination of rotation angle has two bodies arranged movably relative to one another, sensor coils with inductive and alternating current resistance values variable by a relative change of size of portions of the bodies associated with the coils. The bodies include a first body divided into a plurality of regions corresponding to the coils and disassociated with a respective one of the coils. The regions are offset relative to one another in an axial direction and also offset in a radial direction in correspondence with the number of the regions by a certain angle. The coils are formed as wire coils.
