Automatic
measurement on basic magnetization curve and magnetic
hysteresis loop under static state of soft magnetic
material, accurate measurement on static magnetic
characteristic parameters such as initial permeability
μi, maximum permeability μm, saturation magnetic
induction Bs, remanence Br, coercive Hc and hysteresis
losses Pu.
Windows measurement software applied
simply. It conforms to China National Standards GB3657 -
83, industry standard SJ / T10281 - 91 and international
standard IEC60404 - 4.
In accordance with
measuring principle of ballistic method, combine
computer control technology, A/D and D/A, replace
conventional ballistic galvanometer with electronic
integrator, realize analog ballistic method measurement
under microcomputer control, can completely eliminate
non-instant error caused by ballistic galvanometer in
classical ballistic method, with high measurement
accuracy, fast speed and good repeatability, can
eliminate the influence of various artificial factors,
and supply reliable basis for research on material
magnetization process. | |
