Principle
BHS Series
For the convenience of classification, all kinds of magnetic materials are classified into three types according to coercive force Hc: soft, semi-hard and hard. This equipment can be divided into: soft magnetic material measurement, semi-hard/hard magnetic material measurement. Three types of versatile models for measuring all types of materials. The unit components of each model are designed as common modules by inserting and adding methods, and easy to expand the measurement range.
AC magnetization automatic measurement and analysis equipment
Not only the B-H curve, the magnetic flux density, the differential magnetic flux, the magnetic boundary, etc. can be recorded.
| Material Type | Measurable characteristic data |
| Commercial frequency soft magnetic material, high frequency, Soft magnetic material, magnetic film material | Dynamic magnetic properties through AC magnetization |
Principle
AC-BH Series
The integrator of e2∝dΦ/dt is output to the VER vertical axis of the digital oscilloscope by the calculation of ∫e2dt∝Φ, and the AC excitation current waveform is output to the HOR axis of the oscilloscope, and set to XY display than can observe the BH curve.
