Abstract
A sensor arrangement has a sensor array (SA) with a first, a second, and a third sensor focus (SSP, SSP, SSP), which are located along a main linear direction (L) and in which the third sensor focus (SSP) is located in the middle between the first and second sensor foci (SSP, SSP). Individual sensor devices (SM, SM, SM) with magnetic field sensors that provide a first, second, and third set of sensor signals are correlated with the sensor foci (SSP, SSP, SSP). A first and a second channel signal (CH, CH) are derived as a function of the sets of sensor signals in a processing device (PRC) via a first and a second combination device (K, K). An evaluation unit (EV) is configured to derive a phase angle as a function of the channel signals (CH, CH).
