Magnetostrictive position measuring device with high measurement precision

DETAILED DESCRIPTION The aim of the present invention is to provide a magnetostrictive transducer with high measurement precision which can be manufactured with a structure which is simplified with respect to conventional transducers.
Within the scope of this aim, an object of the present invention is to provide a magnetostrictive transducer with high measurement precision in which the mechanical wave is damped in an optimum manner in order to avoid interfering with the measurement provided by the transducer.
Another object of the present invention is to provide a magnetostrictive transducer with high measurement precision in which the external vibrations to which the transducer can be subjected do not affect measurement precision at all or at the most minimally.
Another object of the present invention is to provide a magnetostrictive transducer with high measurement precision which is highly reliable, relatively easy to manufacture and at competitive costs.
This aim, these objects and others which will become apparent hereinafter are achieved by a magnetostrictive transducer with high measurement precision, comprising a containment tube which accommodates a magnetostrictive tube inside which a conducting wire is accommodated, transducer means being provided at one end of said magnetostrictive tube, means for detecting the signal acquired by said transducer means being connected to said transducer means, characterized in that said magnetostrictive tube is connected to said containment tube by conducting means which are suitable to provide electrical continuity between said conducting wire accommodated in said magnetostrictive tube and said containment tube.
