Zusammenfassung:A thickness measuring instrument for measuring the thickness of the coated layer on the surface of iron workpiece is composed of magnetic field generator, magnetic field intensity sensor, amplifier and display. The magnetic field intensity acting on said sensor is associated with the thickness of coated layer (magnetic gap), so the thickness can be indirectly measured.
