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 National Standards GB 3656-83, GB 3657-
83, GB/T 13012-91, GJB 937-90, industry standard SJ/T 10281-91 and international standard IEC 60404-4,
IEC 404-7.
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.
Ÿ Testing sample varieties: soft magnetic ferrite, permalloy, amorphous, nano crystal, iron dust core,
electrician ferrite and stalloy.
Ÿ Testing sample shapes: toroid, E and U closing
samples, and strip (bar) and chip open samples.
Ÿ Closing sample direct winding measurement:
sample, magnetizing coil (N1) and measuring coil
(N2) form a no-load transformer.
Ÿ Measure magnetic field intensity through measuring magnetizing current, magnetic field lock
precision as high as 0.1%.
