Abstract

A sizing device having a reading head whose scale is moved linearly in accordance with relative displacement of a pair of measuring feelers simultaneously moved in opposite direction so as to be brought into diametric contact with a workpiece. Signals transmitted from the reading head are applied to a reversible counter which calculates the span between the feelers and whose count is compared by a comparator with a desired size stored in a register. The comparator generates a sizing signal at its output when the size of the span between the feelers accords with the desired size and this size is digitally indicated on an indicator.
