MATS-2010SD  Hysteresisgraph
MATS-2010SD automatically measure the Magnetizing Curve and Hysteresis Loop of the soft magnets under static(DC) condition. Precisely measure and show static magnetic characteristics, such as initial permeability(μi), max permeability(μm), saturated flux density(Bs), remanence(Br), coercivity(Hc) and hysteresis loss.  
 
According to the classic ballistic method principle, MATS-2010SD combines the computer control   and A/D、D/A, replace the conventional ballistic galvanometer with electronic integrator, achieve the analog ballistic measurement under microprocessor. It completely removes the non-instant error and is more accurate, faster and with a good repeatability. It removes various kind of artificial factors, offers a stable basis to study the magnetizing progress.

2. Sample shape: ring, toroid, E and U closed circuit.
3. Closed circuit samples directly winded: samples, magnetized coils(N1), measuring coil(N2) form a non-load transformer.
4. Measure open-circuit samples need fixtures(solenoid or permeameter optional), its inner field is measured by a built-in magnetic potentiometer(optional).
5. Measure the field strength through testing the magnetizing current, field locking accuracy up to 0.1%.
6. Measure the flux density by electrical integrator, the integrator ZERO drift self-correcting by software.
7. Measuring method: analog ballistic and magnetic field sweep.
8. 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.  
9. 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. (This method is only used by Linkjoin, highly approved the accuracy)
10. Automatic demagnetizing function before μi test, demagnetizing with saturated AC 10Hz.
11. 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.
12. 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.
