Patent ID: 8395382

Claim:
A sensor device ( 30 ) comprising: at least two magnetic sensor elements (R 0 , R 1 , . . . , Rn−1) connected in series or in parallel, each magnetic sensor element (R 0 , R 1 , . . . , Rn−1) having a sensitivity (S 0 , S 1 , . . . , Sn−1), wherein the sensitivity (S 0 , S 1 , . . . , Sn−1) of each magnetic sensor element (R 0 , R 1 , . . . , Rn−1) differs from the sensitivity (S 0 , S 1 , Sn−1) of any other magnetic sensor element (R 0 , R 1 , . . . , Rn−1), each of the at least two magnetic sensor elements (R 0 , R 1 , . . . , Rn−1) outputs a sensor signal over a rang of a sensed parameter, and a sum of each of the sensor signals of the at least two magnetic sensor elements (R 0 , R 1 , . . . , Rn−1) fits a non-linear function of the sensed parameter over the range of the sensor device ( 30 ).
