MAGNETIC THICKNESS GAUGE OF DUAL-LAYER COATINGS MTGD-1


      The device measures two wide ranges of thicknesses of ingredients of dual-layer chrome-nickel coatings (chrome on nickel, and nickel under chrome) on non-ferromagnetic and weak-magnetic basis.
      The device is completed with two magneto-dynamic transducers. Magnet parameters of one of them are chosen for providing of high resolution for chrome thickness; the resolution is constant in the given range of variation of nickel thickness, and in this range one can test chrome thickness independently of nickel thickness. Magnet parameters of other transducer are chosen for providing of high resolution for nickel thickness, minimal resolution for chrome thickness and approaching of nickel magnetization in the volume of informative area to saturation magnetization, therefore one can test thickness of nickel under chrome with elimination or minimization of error that is conditioned by nickel structure.
