Electromagnetic field measurement system HG 200

polarizationfor magnetostrictive materialsfor industrial applications

• Measurement of all hard magnetic materials (AlNiCo, ferrite, SmCo, NdFeB, plastic composite) • Measurement with constant flux alteration d/dt • Measurement with J-compensated surrounding coils, pole or field coils • Measurement at higher temperatures up to 200°C • Fully computer-controlled measuring system • Real time display of hysteresis during measurement • BROCKHAUS® MAG Expert software for measurement, presentation and integration into QM systems • Windows desktop 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).
