Multi-Frequency Single Sheet Tester (MF-SST)

We are delighted to present Vienna Magnetics Precision Multi-Frequency Single Sheet Tester.

It is a simple and rapid desktop apparatus, for physically correct measurements of magnetic losses of electric steel and amorphous ribbons, for up to 10 kHz compact.

Some of the advantages of the Multi-Frequency Single Sheet Tester are:

1. The strongly enlarged range of frequency, the extreme reduction of mass by means of a small high-frequency yoke.
2. The reduced size of desktop-compatible apparatus by means of reduced sample width to 17 cm as being sufficient for the homogeneous structure of modern steel types (50 cm sample length, like IEC Standard 60404-3), more exact true-field air-flux compensation.
3. The simplified rapid test procedures (more than 10 measurements per minute possible), an automatic scan over large induction range and instantaneous power functions.
4. Instant output of results by laptop PC as well as by A4 protocol printer (extra data processing possible via text files).
5. To sum up, Vienna Magnetics Precision Multi-Frequency Single Sheet Tester is a perfect solution, for direct, simple, accurate, rapid and cost-effective measure­ments of losses, over a very large frequency range, for all types of material, i.e. NO and GO FeSi, as well as amorphous or nano-crystalline rib.
6. As the most significant feature, the novel MF SST will comply at present the developed IEC standard of SST with H-coil, with respect to reduced sample width and test procedure.
7. Thus, the MF SST represents the “tester of the future”, replacing error-prone magnetization-current apparatuses.

Further, applicability for both crystalline and amorphous materials does opens “universality of loss measurement”, as a future basic concept.

Examples of Applications

1. Representative data of GO transformer materials, up to high B of 1.9 T, for f up to 1 kHz.
2. Data of NO steel for f up to 10 kHz, including anisotropy studies.
3. Comparative tests of amorphous ribbon.
4. Rapid tests on effects of cutting and slitting.
5. Study of magnetic power functions: dissipative Bloch wall motions / non-dissipative atomic moment orientations.
6. Ultra-rapid steel comparisons, of all kinds.
