trasdutture metallic tape for measures micrometriche linear magnitudes

摘要

The invention relates to a transducer for the micrometric measurement of linear quantities comprising a support rule, a scale in the form of a very thin continuous metal tape which is kept suspended at its ends under a predetermined constant tension and on which the measurement notches are directly engraved, and a reading head comprising a tape guide groove in which the tape slides freely during the movement of the head relative to the support rule.
