INSTRUMENTATION AND SIGNAL CONDITIONING FOR BARKHAUSEN NOISE MEASUREMENT

  • Abstract:
    The aim of this work is to describe an improved Non Destructive Testing (NDT) methodology based on the analysis of Barkhausen noise (BN). A purposely designed probe has been realized, that allows the acquisition of the Barkhausen noise together with the magnetic induction flux experimented by the pick-up coil core plus the material under test. The basic idea is to support the BN analysis with information related to the hysteresis cycle; experimental results show how a multivariate approach can lead to a better resolution and repeatability.
