Magnetostriction Tester MST 500 Operating principle The magnetostriction tester is a supplementary module for connection to BROCKHAUS electrical sheet measuring systems. Magnetostriction is one of the causes of buzzing which arises during the operation of transformers. In a single sheet sensor the measuring sample is exposed to a defined external magnetic field. Magnetic domains within the sample change with increasing magnetization which results in elongation. With the aid of a laser-supported longitudinal measuring system the elongation is recorded and displayed via a software programme. Magnetostriction...
