Abstract

A rotatable capacitance sensor preferably constructed of a generally cylindrical body mounted on bearings to a carriage assembly. The body has a number of parallel, spaced apart conductive plates having edges extending through the exterior body surface, and alternate ones of the plates are connected via a bearing to a conductor in one part of the carriage assembly, and the remaining ones of the plates are connected via a bearing to a second conductor in another part of the carriage assembly.
