A device and method for determining and/or measuring the shape of a workpiece, in particular its thickness or surface form, comprises at least one measuring pin 4 the or each of which is to point towards the workpiece 2, is movably mounted in a housing 3 to which the workpiece 2 is relatively movable and has a central bore 7 through which the workpiece 2 is to be jetted with compressed gas in such a manner that a local pressure is created between the measuring pin 4 and the surface 1 of the workpiece 2, as a result of which the measuring pin 4 maintains a constant distance 's' from the surface 1 of the workpiece 2. <IMAGE> |
