The transducers are arranged in such a way that the respective measuring ranges are contiguous and the device has a total measuring range which is substantially larger than the measuring range of a single transducer. By suitably changing the mutual arrangement of the parts of the transducers, it is possible to vary the total measuring range of the device, the maximum extent of which corresponds substantially to the sum of the measuring ranges of the two transducers.
A device for measuring and checking dimensions of a mechanical piece comprises one or more contactless inductive transducers fixed to a support frame in such a way as to face the surface to be checked. Each transducer includes a core made of a particular ferromagnetic material called MUMETAL® and windings arranged about at least one portion of the core. The high workability of this material enables to obtain cores whose dimensions and shapes are suitable for the specific type of checking which has to be performed.
