Inductive incremental displacement sensor for determining displacement of object relative to another object, particularly for feed through, has two sensor units with one inductive sensor and another inductive sensors

摘要

The inductive incremental displacement sensor has two sensor units (40,50) with an inductive sensor (41,51) and another inductive sensors (42,52). The two sensor units supply a switching signal that belongs to a conductive area (32) of the partition groove, if the difference or the ratio of the detection signals of the inductive sensors is smaller than the determined threshold. The detection signals of the inductive sensors are generated by the conducting areas. Independent claims are also included for the following: (1) a method for determining the displacement of an object relative to another object (2) an inductive sensor unit for space independent determination of a lateral position of an object, particularly a conducting area or a periodically graduated track of an incremental encoder.
