Magnetic induction thickness measurement
WebThe probe or an instrument with integrated probe is placed directly on the coating to be measured. The coating thickness is displayed on the instrument. In 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. WebElectromagnetic testing is a general test category that includes Eddy Current testing (ECT), Alternating Current Field Measurement (ACFM) and Remote Field testing. All of these techniques use the induction of an electric current or magnetic field into a conductive part, then the resulting effects are recorded and evaluated.

WebFeatures Magnetic induction (F), measuring the thickness of non- magnetic materials (e.g. Paint, plastic, porcelain enamel, copper, zinc, aluminum, chrome etc.) on ... WebThe magnetic induction measurement method according to ISO 2178 is an electro-magnetic method for measuring the thickness of magnetically-neutral coatings on magnetic base material. It enables the non-destructive testing of coat thickness or material – for example galvanic coats of chromium, zinc, copper or aluminum on steel and iron.
WebIn general, magnetic coating thickness measurements on rough surfaces only make sense if the coating is at least twice as thick as the roughness peaks are high. For better accuracy, Fischer offers probes with particularly large poles, as well as 2-pole probes.
