Patent ID: 8766625

Claim:
An absolute linear segment or revolution counter, comprising: an excitation magnet (EM 1 ); said excitation magnet (EM 1 ) includes a main field; an induction coil (SP), said conduction coil wound around an axis; a Wiegand element (WE), said Wiegand element being a ferromagnetic element (FE) which is surrounded axially by said induction coil (SP); said induction coil (SP) includes a length, said length of said induction coil includes a middle, said middle of said length of said coil (SP) is located in the rotational or movement axis, respectively, within said main field of said excitation magnet (EM 1 ); a first sensor element (SE); a counter unit having a non-volatile data memory; control logic; said induction coil supplying electrical energy to said control logic, said counter unit and said sensor element; a magnet back connection, said magnet back connection is a ferromagnetic back connection body; said Wiegand element (WE) resides concentrically on said axis of said coil (SP); said Wiegand element transitions across the main field of said excitation magnet, or, said Wiegand element transitions in the direction of said main field of said excitation magnet (EM 1 ) in each revolution; and, said induction coil, said counter, said first sensor element, said logic, and said Wiegand element determine a counter value.
