<p>The device comprises a bridge and a measuring-result converter for measurements of moment of rotation. Solar cells are distributed on the measuring-hub and, on being illuminated by means of fixed light-sources, produce a voltage for supplying the measuring-parts. Incandescent or fluorescent tubular are used, covered by a reflective screen. The device avoids the short-comings of the induction voltage supply, in which the distance between effective signal and interference signal may be reduced to half the value typical for the system, and accurate measurements are made possible, even for high shaft-dias. and high speeds of revolution without requiring maintenance and supervision.</p> |
