METHOD FOR NON-CONTACT LINEAR POSITION MEASUREMENT

摘要

The invention relates to non-contact linear position measurement between two components which may be displaced relative to each other, by means of a method using a magnet sensor fixed to the first component, above which a permanent magnet is fixed to the second component. Said sensor gives a signal comprising a maximum level, a minimum level and an intermediate level, between the above. The signal range is determined as the difference between the maximum value and the minimum value and from the given signal a normalised signal is generated by division with the signal range and the normalised signal used to determine the non-contact linear position measurement.
