This equipment is an automated magnetic inspection and measurement equipment for multipole magnetic rings, mainly used for measuring the surface magnetic distribution curve of multi-level magnetic rings such as ferrite, plastic magnet, and neodymium iron boron. The device can automatically detect the peak, angle, area, width, and half width of each magnetic pole. It can also automatically determine the number of poles of the magnetic ring and the polarity of the magnetic pole, and perform statistical analysis on the test results, calculating the maximum, minimum, average, and standard deviation of each parameter. It can also draw X-Y curves and polar coordinate curves. The test report has both Chinese and English formats, which can simulate display, easily adjust size and margins, add user logos and enterprise names at will, and can also be converted into image files.
