The magnetic induction method allows measurements of paint, varnish, plastic, rubber, ceramics, zinc plating and galvanic coatings on steel. The eddy current method allows you to measure insulating coatings (paint, lacquer, plastic, anodizing) on non-ferrous metals. The coating thickness gauge has a graphicalses are generally used for coating thick-ness measurement: the magnetic method in accordance with ISO 2178 and the ed-dy current procedure in accordance with ISO 2360. The magnetic or magnetic induction pro-cedure is used to make non-destructive measurements of the thickness of non-magnetic coatings on magnetic substrates Overview of magnetic and eddy current measurement principles. When it comes to coating thickness measurement, two commonly used principles are magnetic induction and eddy current.Let’s take a closer look at each of these principles: 1️⃣ Magnetic Induction: Magnetic induction is a widely employed method for measuring coating thickness.It . The sheet metal supplier applies the zinc coating either by galvanic deposition or in a zinc dip bath. If the zinc coating thickness is uniform, the thickness of the subsequently applied paint coating can be measured using a conventional magnetic induction coating thickness measurement instrument.
While standard paint and powder coating thickness measurement requirements can be accomplished using the magnetic induction or eddy current methods, some situations require a different technique. The phase-sensitive eddy current method is well suited for copper thickness measurement in PC board boreholes and surface copper thickness measurement .
Traditionally, the manufacturer’s calibration of magnetic induction thickness gages, as well as two-point calibration by the user before measurements are carried out using dielectric thickness measures, while for tested metal coatings, the electrical conductivity \({{\sigma }_{{\text{c}}}}\) can vary in the range from 7 to 63 Ms/m, depending on the material. Magnetic induction instruments use a permanent magnet as the source of the magnetic field. A Hall-effect generator or magneto-resistor is used to sense the magnetic flux density at a pole of the magnet. . The primary purpose of coating thickness measurement is to control cost while ensuring adequate coverage and should be a routine event for .The PosiTector 6000 is a rugged, fully electronic coating thickness gauges use magnetic and eddy current principles to measure coating thickness on ALL metals, accurately and quickly . Magnetic induction instruments use a permanent magnet as the source of the magnetic field. A Hall-effect generator or magneto-resistor is used to sense the .
The magnetic induction measurement method works by generating a low-frequency magnetic field that is produced by excitation current I~. A measurement coil μmeasures the resulting magnetic field. . Sample . • Magnetic induction measurement. An excitation current in the probe generates a low-frequency magnetic field which spreads throughout the magnetisable base material. The non-magnetic coating weakens the magnetic field. The reduction in its strength is used to determine the thickness of the coating. • Amplitude-sensitive eddy current process

Precision Instrument Co is a coating thickness measuring . Two different non-destructive processes are generally used for coating thickness measurement: the magnetic method in accordance with ISO 2178 and the eddy current procedure in accordance with ISO 2360. The magnetic or magnetic induction procedure is used to make non-destructive measurements of the thickness of non-magnetic coatings on .
The Magnetic Induction Method is widely used in several industries for non-destructive coating thickness measurement on ferrous metal substrates. Here are key areas where this process is commonly applied. Non-magnetic coating material on magnetic base material. Electroplated layers of chromium, zinc, copper or aluminum on steel and iron 4.2 Magnetic— Magnetic-type gauges measure either magnetic attraction between a magnet and a coating or its substrate, or reluctance of a magnetic flux path passing through the coating and substrate. These gauges are designed to measure thickness of a nonmagnetic coating on a magnetic substrate. MAGNETIC The magnetic technique is used to nondestructively measure the thickness of nonmag- netic (including organic) coatings on ferrous substrates (i.e., steel and iron). Gauges use one of two principles of operation: magnetic pull-off or magnetic/electromagnetic induction.
The galvanize coating is applied by the sheet metal supplier either by hot-dip galvanizing or by electrogalvanizing. If the zinc coating thickness were uniform, the thickness of the subsequently applied paint coating could be measured using a conventional magnetic induction coating thickness measurement instrument.coating thickness measuring instru-ments are available for use in the plating industry that can help to minimize plating failures and control costs. These instruments employ a . induction (electronic). Magnetic Pull-Off Gages Magnetic pull-off gages consist of a permanent magnet, a calibrated spring and a graduated scale. The attractiveIn ISO 2178:2016 the term "coating" is used for material such as, for example, paints and varnishes, electroplated coatings, enamel coatings, plastic coatings, powder coatings, claddings. NOTE This method can also be applied to the measurement of magnetizable coatings on non-magnetizable base metals or other materials (see ISO 2361).
