Measuring error by misalignment of the position magnet
Placement and alignment of the position magnet
For non-contact sensor models air gap and alignment of sensor and position
magnet has to be observed. The linearity will degrade in case of misalign-
ment. Also external magnetic fields and magnetized materials nearby can
effect the measuring result.
