Distance measuring device for determining separation of object from datum position

摘要

The reference point (10) and variable measurement position (1) may lie on a straight or curved track. The distance is measured along the magnetic flux (9) over the surface (2) of a conductor path generating a length dependent magnetic field. There are 2 conductors (3) of equal length with interlaced contacts (4) that are joined by the pressure of an electrical conducting object (5) allowing the measured position to be established.
