    Abstract: A method includes moving (404) a first sensor assembly (108, 110) to a plurality of cross direction positions (500, 600) relative to a second sensor assembly (110, 108), where the first and second sensor assemblies are configured to move in the cross direction relative to a web (102) of material. The method also includes, for each of the plurality of cross direction positions, determining (406) a sensor value associated with a sensor source (212a, 212b) disposed at the second sensor assembly as measured by a sensor receiver (212b, 212a) disposed at the first sensor assembly. The method further includes determining (410) a starting alignment position (500a, 600a) of the first sensor assembly to be a first cross direction position where a difference between the sensor value at the first cross direction position and a corresponding sensor value at one or more adjacent cross direction positions is a minimum.

    Abstract: A gap and displacement magnetic sensor system for scanner heads in paper machines or other systems includes a multiple-sensor assembly (414b). The multiple-sensor assembly includes multiple magnetic field orientation sensors (514x-514z) configured to capture measurements of a magnetic field (550 552) in order to identify (i) a displacement of first and second scanning sensor heads in a first direction (X-Direction), and (ii) a gap separation of the first (410a) and second scanning sensor heads (410b) in a second direction (Z-Direction), and (iii) a displacement of the first and second scanning sensor heads in a third direction (Y- Direction). At least one of the magnetic field orientation sensors (514z) is disposed offset from a centerline (552) of the magnetic field such that an output from the at least one magnetic field orientation sensor indicates a combination of the gap separation and the displacement in either the first direction or the third direction.
