    Tips: Magnetic induction measurement principle of coating thickness gauge

    The thickness of the coating is measured by the magnitude of the magnetic flux flowing from the probe through the non-ferromagnetic coating into the ferromagnetic substrate. The size of the corresponding magnetoresistance can also be measured to indicate the thickness of the coating. The thicker the coating, the greater the magnetic resistance and the smaller the magnetic flux. The paint thickness gauge based on the principle of magnetic induction can in principle measure the thickness of the non-magnetic coating on the magnetic substrate. Generally, the permeability of the substrate is required to be above 500. If the cladding material is also magnetic, the difference between the permeability and the base material is required to be large enough (such as nickel plating on steel). When the probe with the coil on the soft core is placed on the sample to be tested, the coating thickness gauge automatically outputs the test current or test signal. Early dry film thickness gauges used pointer gauges to measure the magnitude of the induced electromotive force. The paint depth gauge amplified the signal to indicate the thickness of the coating. In recent years, circuit design has introduced new technologies such as frequency stabilization, phase lock, and temperature compensation, and used magnetoresistance to modulate the measurement signal. It also uses a patented integrated circuit and introduces a microcomputer to greatly improve the measurement accuracy and reproducibility (almost an order of magnitude). Modern magnetic induction coating thickness gauges have a resolution of 0.1 micron, an allowable error of 1%, and a range of 10mm. Magnetic induction measuring principle Coating thickness gauge can be used to accurately measure the paint layer of steel surface, porcelain, enamel protective layer, plastic, rubber coating, including nickel chromium and other non-ferrous metal coating, as well as various chemical and petroleum industry anticorrosive coating.
