Operating principles

Determination of the magnetic properties of hard magnetic materials.

Measuring procedure according to IEC 60404-5.

This process runs with constant flux alteration d/dt and avoids interference caused by eddy currents and phase displacement between the field strength and polarization measurements.

The measurement is highly accurate and has high reproducibility. Processor-controlled monitoring and regulation of the increase in current.

Processing of the measured values via MAG Expert software for measurement, presentation and integration into QM systems.

Consisting of measuring table with voltage supply unit and measuring electronics, electromagnet and computer hardware with MAG Expert evaluation software.

Surrounding coils or pole and field coils as measuring fixture with EPROM for automatic probe identification. False measurements due to wrong input of parameters are ruled out. The electromagnet has interchangeable pole pieces and is supplied with two sets of these measuring poles (Ø 80 mm and Ø 92 mm).

The hystograph measuring system can be complemented with different measuring coils and poles, electromagnets for high field strengths and field homogeneity as well as with a system for measuring at temperatures up to 200°C, consisting of temperature control unit, heating poles and temperature surrounding coil.

Measuring poles with diameters between 70 - 80 mm. Pole coils with diameters between 3 – 9 mm. J-compensated surrounding coils and temperature surrounding coils with diameters 10 – 40 mm. All coils and measuring poles in special sizes and shapes available.
