Abstract

A magnetic sensor arrangement (100) for determining information being indicative of characteristics of a mechanical component (104) is provided. The magnetic sensor arrangement comprises a first magnetic sensor (101) being adapted to sense a signal being associated with a periodic changing magnetic field being generated due to a relative movement of the mechanical component in relation to the magnetic sensor arrangement, a second magnetic sensor (102) adapted to sense the signal being associated with the periodic changing magnetic field, wherein the first magnetic sensor (101) is arranged at a fixed distance to the second magnetic sensor (102), and a determination unit (103) being coupled to the first magnetic sensor (101) and the second magnetic sensor (102) and being adapted to receive the output signal of the first magnetic sensor (101) and the output signal of the second magnetic sensor (102), wherein the output signal of the first magnetic sensor (101) is phase-shifted to the output signal of the second magnetic sensor (102), to compare the output signals for determining the absolute phase of the signal being associated with the periodic changing magnetic field, and to determine information being indicative of characteristics of the mechanical component based on the determined absolute phase of the signal being associated with the periodic changing magnetic field.
