Patent ID: 6922051

Claim:
An inductive sensor, comprising: a fixed housing; a body moveable on said fixed housing, said body having an inductive transmission element operative for generating an alternating magnetic field flux during movement of said body said flux passing over a flux path area of said fixed housing; and at least one conductor loop arranged on the fixed housing so as to extend along a measurement length of said housing, said conductor loop including a feed line extending along the measurement length and a return line, said return line having a path which at regular intervals of said measurement length alternates into and out of said flux path area, a permeation of said return line at a given path location by the flux of said flux region inducing a loop output voltage indicative of a measurement length position of said body on said fixed housing, the return line having a width in areas permeated by large amounts of flux that is proportional to an expected output value associated with a desired position value, thereby producing an analog output signal.
