For MATS-2010SA, under continuous frequency of 1 kHz to
500 kHz, automatic measurement of magnetic hysteresis loop of the soft magnetic
materials such as silicon steel, precision alloy, non-crystal and
ferrite, accurate measurement on the dynamic magnetic characteristic parameters
such as amplitude permeability μa, loss angle δ, loss iron Pc, remanence Br and
coercivity Hc.
Windows measurement software applied simply. It conforms
to China National Standards GB 5026-85, GB 3658-90, GB/T 9632.1-2002, GB/T
19346-2003, industry standard SJ/T 10281-91 and international standard IEC
60367-1, IEC 60404-6.
The controlling of computer and A/D sampling
replace the traditional analog bridge, frequency meter, ammeter, voltage meter,
power meter, the whole testing process is automatic completed.
·Testing
sample varieties: soft magnetic ferrite, permalloy, amorphous and nano
crystal.
·Test
sample shapes: toroid, E and U shapes.
·Test
samples with closed magnetic circuit can be directly winded and measured on
samples. Magnetizing coil (N1) and measuring coil (N2) form a no-load
transformer.
·Non-inductive
resistance connected on magnetizing coil loop to determine magnetizing current
and magnetic field intensity through the measurement of pressure drop on non
inductive resistance, magnetic field peak value can be locked through digital
feedback, magnetic field lock precision 0.5%.
·Magnetic
induction obtained through digital integration of coil measuring voltage,
magnetic induction peak value locked through digital feedback, magnetic
induction lock precision 0.5%.
·Power
source and sampling amplifier integrated into a casing with simple interface:
one RS232 interface connected to the computer, two way voltage alarm connected
to high speed A/D card.
·Different
power sources can be selected according to different test requirements: 1 kHz ~
300 kHz or 500 kHz, 5 kHz or 10 kHz ~ 100 kHz or other frequency ranges
customized.
·Measuring
dynamic hysteresis loop through volammetry and digital integration can
accurately measure dynamic magnetic characteristic parameters such as μa, δ, Pc,
Br and Hc, and calculate μ', μ'', μL, μR, Q and
AL, etc.
·Automatic
and continuous measurement up to 255 testing points, the testing time of every
testing point is about 12 seconds, fixed-frequency or fixed
Bm optional in multipoint test.
·Powerful
function of the software, the technical request to the testing staff is very
low.
