General Features of DC Hysteresis Graph (DX-2012SD)
- 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.
