<p>Apparatus for gauging surface profile of a workpiece comprises means for maintaining under tension an element which extends at least over the length of the surface to be gauged and which is effective to provide a reference surface against which the surface under test can be compared for gauging, a displacement transducer effective to produce a signal representative of the separation between the surfaces together with means adapted to support the transducer for traverse along the length of the surface to be gauged.</p> |
