Magnetic thickness gauge

The structure of the magnetic thickness gauge is integrated, which can be operated with one hand during measurement. Because it is made using the principle of electromagnetic induction, it is suitable for measuring the thickness of non-magnetic coatings on various magnetic metal substrates. It can also measure the thickness of various coatings on steel (except nickel plating), coatings, enamel, plastics, etc. It can also be used to measure the thickness of various metal foils (such as copper foil, aluminum foil, gold foil, etc.) and non-metallic films (such as paper, etc.). Magnetic thickness gauges can be used in industries such as production, acceptance inspection, and quality supervision to test whether products comply with national standards.
The principle of ultrasonic pulse reflection is the main basis for the thickness measurement of the ultrasonic thickness gauge. When the ultrasonic wave emitted by the ultrasonic thickness gauge reaches the surface of the object, the pulse is returned when it meets the surface of the measured object, and the measured time can be measured. The thickness of the coating of the measured object, the ultrasonic thickness gauge is suitable for materials where sound waves can propagate at a uniform speed. The accuracy of the thickness gauge does not need to be tested by yourself. Just open the manual or find the specific name on the nameplate of the thickness gauge. Precision.In real life, the accuracy of ordinary thickness gauges is 0.1mm, 0.01mm, and 0.001mm. The third type is generally a thin-film thickness gauge, which requires higher accuracy. In addition, the accuracy of coating thickness gauges is generally 0.001mm. The accuracy of measuring thickness is less than 0.020mm, which is very poor. Some domestic thickness gauges have 4-5 standard sheets, and different thicknesses have Different standard films.
