摘要： A diameter measuring gauge for machine tools comprising two opposed feelers both movable with respect to one another. The feelers are mounted on arms carried by sleeves that slide on a column. The arms are biased in so that the feelers contact the workpiece with the proper pressure. A hydraulic cylinder coupled to the arms drives the two arms until the feelers make initial contact with the workpiece, then the hydraulic pressure is removed. Measurement is accomplished by a pair of windings carried by the arms in juxtaposition to each other to electrically interact to produce an electrical signal proportional to the diameter of the workpiece.
