Operating principles :

Determination of the characteristic properties of all magnetic materials.

Measuring process according to IEC 60404 ff. or to customer specifications.

Highly accurate measurements with very good reproducibility. Process-controlled monitoring and regulation of the increase in current.

When measuring hard magnetic materials the process runs with constant flux alteration d/dt and avoids interference caused by eddy currents and phase displacement between the field strength and polarization measurement.

With soft magnetic materials the measurement takes place with sinusoidal induction. Processing of the measured values with MAG/MPG Expert software for measurement, display and integration into QM systems.

Consists of measuring table with power supply unit and measuring electronics, electromagnet, Epstein frame, measuring system and computer hardware with MAG/MPG Expert evaluation software.

For measuring permanent magnets: J-compensated coils with a thickness of 1mm and diameters of 10 – 40 mm, pole measuring coils with diameters of 3 – 9 mm, as well as special sizes and shapes.

For measuring soft magnetic materials: SST measuring sensors for the quality control of strips, sheets, slit strips in all manufacturing widths; no complex sample preparation required.

Punched part sensor for nondestructive testing of punched parts in all geometries, e.g. when testing punched parts for motors. Ring core testing module for testing the magnetic properties of ring cores, stators or transformers directly on the component under manufacturing conditions.
