Soft Magnetic Material Dynamic Hyteresisgraph System
   Model WATS-2010SD

Automatic measurement on basic magnetization curve and magnetic hysteresis loop under static state of soft magnetic material, accurate measurement on static magnetic characteristic parameters such as initial permeability μi, maximum permeability μm, saturation magnetic induction Bs, remanence Br, coercive Hc and hysteresis losses Pu.

Windows measurement software applied simply. It conforms to China National Standards GB3657 - 83, industry standard SJ / T10281 - 91 and international standard IEC60404 - 4.

In accordance with measuring principle of ballistic method, combine computer control technology, A/D and D/A, replace conventional ballistic galvanometer with electronic integrator, realize analog ballistic method measurement under microcomputer control, can completely eliminate non-instant error caused by ballistic galvanometer in classical ballistic method, with high measurement accuracy, fast speed and good repeatability, can eliminate the influence of various artificial factors, and supply reliable basis for research on material magnetization process.

System Specifications

Adopt ballistic method measurement, technical indices as follows:

Parameters measured Bs(%) Br(%) Hc(%) Pu(%) μ m(%) μ i (%)
Uncertainty (k=2) 1 1 1.5 1 2 5
Repeatability (constant temperature) ± 0.5 ± 0.5 ± 0.5 ± 0.5 ± 1 ± 3

When testing hysteresis loop with scanning method, H and B measuring errors can be estimated as:          B: 1% + 1/2 LSB         H: 1% + 1/2 LSB
