ABSTRACT:
A position sensing and display means for use on a weighing scale includes two stationary spaced conductive plates to which out-of-phase oscillations are supplied. A movable conductive plate has a position between the two stationary plates dependent on the weight of an object being measured. The amplitude of the oscillations capacitively coupled to the movable conductive plate is displayed as an indication of the weight of the object.
