A sensor arrangement is described, which comprises at least two half bridges coupled together to form at least a Wheatstone bridge, which sensor arrangement comprises at least two magnetoresistive sensor elements in each half bridge. These sensor elements are sensitive along a measuring direction to the magnetic field strength of an applied magnetic field and are adapted to supply a measuring signal in dependence upon a field component of the magnetic field, denoted as a measuring field and measured in the measuring direction. In each half bridge, at least two of the sensor elements have barberpole structures with a mutually different alignment. The co-ordinates of the sensor elements of at least one of the half bridges and the co-ordinates of the sensor elements of at least another one of the half bridges are chosen to different to a predetermined extent along an axis of co-ordinates extending in the measuring direction. This sensor arrangement has a high freedom of interference from magnetic interference fields and thereby ensures reliable operation with simple means, also under complicated conditions.
