Product introduction
FE-2100SD DC measurement system for soft magnetic materials, which automatically measures the basic magnetization curve and hysteresis loop of soft magnetic materials under static (DC) conditions, and accurately measures the initial permeability μi, maximum permeability μm , Saturation magnetic induction intensity Bs, remanence Br, coercive force Hc and hysteresis loss Pu and other static magnetic characteristic parameters.
According to the measurement principle of the impact method, the test system adopts computer control technology and A/D, D/A combination, replaces the traditional impact galvanometer with an electronic integrator, realizes the simulation impact measurement under the control of the computer, and completely eliminates the classic impact In the method, the non-instantaneous error caused by the use of the impact galvanometer improves the measurement accuracy and provides a reliable basis for studying the mechanism of the material magnetization process.
