Patent ID: 8089275

Claim:
A sensor arrangement, comprising: a sensor array with a first, a second, and a third sensor focus, which are located along a main linear direction, wherein the third sensor focus is located in the middle between the first and second sensor focus, the sensor array having a first, a second, and a third sensor devices, which are allocated to the first, second, and third sensor focus and respectively comprise at least one magnetic field sensor, which is configured to provide a sensor signal as a function of a magnetic field strength, wherein the first, second, and third sensor devices are respectively located in such a way that a geometric focus of the at least one magnetic field sensor coincides with the respective allocated sensor focus, and wherein the first, second, and third sensor devices are configured to provide a first, second, and third set of sensor signals; a processing device, having a first combination device, which is configured to derive a first channel signal as a function of the first and second set of sensor signals, and a second combination device, which is configured to derive a second channel signal as a function of the first, the second, and the third set of sensor signals; and an evaluation unit, which is configured to derive a phase angle as a function of the first and second channel signals.
