·Testing sample varieties: soft magnetic ferrite, permalloy, amorphous, nano crystal, iron dust core, electrician ferrite and stalloy.
·Testing sample shapes: toroid, 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, the inner field can be measured by the magnetic potentiometer inside.
·Testing method: analog 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: analog ballistic method to measure hysteresis loop is an exclusive measuring method of our company, can greatly improve the accuracy of Hc and Br.
·Automatic demagnetization function before μi testing, 10 Hz AC saturation demagnetization adopted.
·Select to test single parameter with analog ballistic method to save time, the time of every testing point can be set from 0.1 second to 0.9 second.
·Adopt the B speed feedback, it can automatic regulate the density with the shape of sample magnetic characteristic curve, and curve can also be tested according to the testing point predefined by users.
·Powerful software functions with minimal technical requirements for testing staff. |
