摘要:
A non-volatile, absolute rotation sensor (10) employs a radial guide (24) and spiral guide (20) rotating with respect to each other to move a marker element (25) continuously along the radial guide so that a distance of the marker element along the radial guide provides an indication of shaft movement over multiple turns. A sensor system (56) senses the distance of the marker element along the radial guide to provide an electric output.
