Abstract
A device for checking the weights of individual capsules in a stream of capsules by passing the stream of capsules past a capacitance sensor which measures the capacitance of each capsule as representative of the capsule weight, and passing the stream of capsules past a velocity sensor which measures the velocity of each capsule as representative of the capsule weight. The measured capacitance and measured velocity values are each compared against preset ranges of values, and a capsule is mechanically deflected from the moving stream if the comparison shows either measured value to be outside the respective preset range of values.
