Patent ID: 8525513

Claim:
An angular position measuring device ( 20 ) comprising: a moving magnetic element ( 12 ) for which a rotation angle is to be measured; a magnetic sensor ( 10 ) cooperating with the moving magnetic element ( 12 ), the magnetic sensor comprising exactly two Wheatstone bridges defined by i) one first (R 1 to R 4 ) group of magnetoresistive elements configured as a first Wheatstone bridge and ii) one second (R 5 to R 8 ) group of magnetoresistive elements configured as a second Wheatstone bridge, the first and second Wheatstone bridges for supplying a first and a second measurement signal (Sin, Cos) respectively proportional to the sine and the cosine of twice the angular position (α) of the moving magnetic element; and a processing unit supplying a response (Arctan) corresponding to the angular position of the moving magnetic element from said first and second measurement signals, wherein the magnetic sensor ( 10 ) is arranged offset relative to an axis ( 14 ) of the moving magnetic element, wherein the moving magnetic element ( 12 ) is arranged offset relative to a rotation axis ( 30 ) of said moving magnetic element, by offset values (Angle_R, Distance_R, Angle_A, Distance_A) selected so that the angular measurement range of the magnetic sensor extends beyond 180°, and wherein the processing unit supplies the response (Arctan) corresponding to the angular position of the moving magnetic element from said first and second measurement signals without measurement signals from any further Wheatstone bridges.
