Abstract
An apparatus for measuring the capacitance of tablets of varying shapes and sizes by conveying the tablets along a curved path which includes a zone of travel between the plates of a capacitive sensing device. The tablets are conveyed in a relatively fixed orientation by constructing a guide channel including a fixedly-positioned curved guide spaced away from a rotatable disk, and wherein a resilient clamp is provided above the guide channel so as to compress the tablet against the rotatable disk during its path of travel.
