Patent ID: 7855552

Claim:
A rotation angle sensor ( 1 ), said sensor comprising: a housing ( 2 ); a sensor element ( 3 ) located in the interior of the housing ( 2 ); a rotation indicator ( 4 ), located outside of the sensor housing ( 2 a ), so it can rotate, and coupled with the sensor element ( 3 ), so it operates in a non-contacting manner through the wall of the housing ( 2 ); and an intermediary element ( 5 ) being rotationally supported in the interior of the housing ( 2 ) between the sensor element ( 3 ) and the rotation indicator ( 4 ), and being coupled to the rotation indicator ( 4 ) in a rotationally fixated, but non contacting manner, wherein the sensor element ( 3 ) is fixed in the housing ( 2 ) in a non-rotatable, spatially exactly defined position relative to the intermediary element ( 5 ), and the sensor element ( 3 ) is a magnetic sensor being coupled to the intermediary element ( 5 ) in a non-contacting manner by means of magnetic interaction wherein the intermediary element ( 5 ) is supported in the housing ( 2 ), whereby it floats on a fluid within the tight housing ( 2 ) as a float ( 25 ), and the pivot axis ( 17 ) is vertically disposed.
