Automatic
measurement on hysteresis loop of soft magnetic material
under dynamic (AC) condition, accurate measurement on
dynamic magnetic characteristic parameters such as
amplitude permeability μa, looss angle δ, iron loss Pc,
remanence Br and coercive force
Hc.
Windows measurement software
applied simply. It conforms to China National Standards
GB3658 - 83, GB5026 - 85 and GB9632 - 88, industry
standard SJ / T10281 - 91 and international standard
IEC60404 - 6.
Analog source (bridge),
frequency indicator, ammeter, voltmeter and wattmeter
are replaced through computer control and high speed A/D
sampling, entire testing process automatically
completed.
Adopt volammetry to measure loss Ps and amplitude
permeability μa and loss angle δ, when test frequency is
50kHz, conduct test on ferrite circular ring sample with
standard size (d1 = 40mm, d2= 32mm, h = 6 ~ 10mm), technical
indices as follows:
