We are delighted to present ViennaMagnetics Precision Multi-Frequency Single Sheet Tester, 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: the strongly enlarged range of frequency, the extreme reduction of mass by means of a small high-frequency yoke, 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, the simplified rapid test procedures (more than 10 measurements per minute possible), an automatic scan over large induction range and instantaneous power functions, instant output of results by laptop PC as well as by A4 protocol printer (extra data processing possible via text files). To sum up, ViennaMagnetics 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 ribbons.
