Epstein Frame



  • Measuring sensor with squared coil arrangement
  • For the quality control of electrical steel and other soft magnetic material
  • Construction according to IEC 60404-2 or according to customized requirements
  • Contra-inductivity to compensate air flux

Measuring sensor system for the quality control of electrical steel and other soft magnetic materials. The BROCKHAUS Epstein frame corresponds to the international standard IEC 404-2. One side of the squared coil arrangement is movable for the simple output of the overlapped Epstein sample.
