Devices (1) with sensor arrangements (10) comprising movable objects (13) for, in response to movements, changing magnetic fields, are provided with a field detector (12) comprising a bridge with two or more elements (21-24,31-34) and a further bridge with two or more elements (35-38) for detecting components of magnetic fields in planes of the bridges. The bridge comprises first properties depending on the movements in Z-directions and second properties depending on the movements in X-directions. The further bridge comprises third properties depending on the movements in Z-directions and fourth properties depending on the movements in Y-directions. The first and third properties indicate that the resistance values of all elements have increased or decreased with substantially the same value. The second and fourth properties indicate that the resistance values of two elements have increased with substantially the same value and that the resistance values of two other elements have decreased with substantially the same value. |
