·Testing sample varieties: soft magnetic ferrite,
permalloy, amorphous, nm crystal, iron dust core, electrician
ferrite and stalloy.
·Testing sample shapes: annular, E and U closing samples,
and strip (bar) and chip open samples.
·Closing sample direct winding measurement: sample,
magnetizing coil (N1) and measuring coil (N2) form a no-load
transformer.
·Measure magnetic field intensity through measuring
magnetizing current, magnetic field lock precision as high as
0.1%.
·Adopt electronic integrator to measure magnetic induction,
zero drift of integrator can be self-corrected through
software.
·Solenoid or permeameter shall be equipped to measure open
samples.
·Testing method: simulate ballistic method and magnetic
field sweep.
·Adopt analog ballistic method to measure basic
magnetization curve, can accurately measure magnetic
characteristic parameters on magnetization curve: μi, μm, Bs,
value μ of any point.
·Adopt analog ballistic method and magnetic field sweep to
measure saturation hysteresis loop, can accurately measure
magnetic characteristic parameters on hysteresis loop: Bs, Br,
Hc and Pu. Special explanation: simulate ballistic method to
measure hysteresis loop is an exclusive measuring method of
our company, can greatly improve the accuracy of Hc and Br.
·Automatic demagnetisation function before μi testing, 10Hz
AC saturation demagnetisation adopted.
·Testing single parameter can be selected in case of
measurement with analog ballistic method to save time, the
time of every testing point can be set as 0.1 second ~ 0.9
second.
·The density of testing point can be self-regulated with B
speed feedback according to the shape of sample magnetic
characteristic curve, curve can be also tested according to
the testing point predefined by users.
·Powerful software functions with minimal technical
requirements for testing staff.
