ABSTRACT:
Electrical circuitry and associated mechanical apparatus are combined to provide a non-contactng transducer for adaptation to an existing mechanical scale for adapting the mechanical scale to an electrically controllable scale. The scale movement sensing apparatus is arranged such that there is no frictional or inertial resistance to movement of any of the mechanical scale parts, while providing a continuously variable range over which a scale weight may be sensed.
