Linear and angular displacement measurement arrangement for a machine part, has a single sensor that detects the extension and position of a measuring structure mounted on the machine part

摘要

Measuring arrangement (1) has a structure (3) mounted on the machine part (6), whose extension and position within the viewing field of a sensor (2) is dependent on the angular and axial position of the machine part. Thus determination of extension and position of the structure permits determination of the axial (a) and angular (r) positions of the machine part itself.
