Abstract:
A magnetic sensor arrangement for determining information indicative of characteristics of a mechanical component has a first magnetic sensor to sense a signal associated with a periodic changing magnetic field generated by relative movement of the mechanical component and the magnetic sensor arrangement, a second magnetic sensor to sense that signal, wherein the first sensor is arranged a fixed distance from the second sensor, and a determination unit coupled to the first and second sensors to receive output signals of the first and second sensors. The output signal of the first sensor is phase-shifted to the output signal of the second sensor, to compare the output signals for determining the absolute phase of the signal associated with the periodic changing magnetic field, and to determine information indicative of characteristics of the mechanical component based on the determined absolute phase of the signal associated with the periodic changing magnetic field.
