Abstract
An inductive sensor for determining a position of a body moveable on a fixed housing includes an inductive transmission element in the body, the transmission element being operative for generating an alternating magnetic field flux. The body is movably arranged such that the flux passes over a flux path area of the housing. At least one conductor loop is arranged on the housing along a measuring length on the housing which measuring length can extend in a linear course or a circular course. At least one conductor loop is arranged on the housing extending along the measuring length, the conductor loop including a feed line and a return line. The return line has a path which at regular intervals of said measurement length alternates into and out of said flux path area. A permeation of the return line at a given measurement path location by the flux of the flux region induces a loop output voltage indicative of a body measurement length position on the housing or of a body angular position on the body.
