Published: 2024-01-18 Views: 次

The IWATSU B-H Analyzer measures a wide range of magnetic performance parameters of soft magnetic materials, including core indicators such as the B-H curve, power loss, and permeability.

The B-H Analyzer is a professional test instrument designed primarily for loss testing of soft magnetic materials such as powder cores, ferrite, and amorphous alloys, making it highly valuable for material R&D and production. The IWATSU B-H Analyzer offered here handles premium materials including sendust and ferrite, with a wide measurement range and resolution up to 16 bit, ensuring accurate test results. The unit is compact and easy to operate, and supports testing of toroidal, EI, and EE samples.

Key Measurement Items

• B-H curve: evaluates the magnetization characteristics of a material via the relationship between magnetic flux density (B) and magnetic field strength (H).

• Power loss (Pc): measures core loss under an alternating magnetic field.

• Permeability (μ): a parameter reflecting the material's ability to conduct magnetic flux.

Specifications

• Over 20 parameters, including maximum flux density (Bm), residual flux density (Br), coercivity (Hc), initial permeability, and phase angle.
