In a measuring coil a material sample is exposed to a defined magnetic field and magnetic flux is created in the sheet steel. The required electric current is supplied by a power amplifier. The current is measured by means of a temperature-stable, low inductivity precision resistor (shunt) or via field coils. Determination of the polarization is by sampling of the induced voltage, conversion and integration. Parallel recording of the H and J sizes with separate analogue-digital converters guarantees absolutely simultaneous measurement.
From the differentiated and integrated parameters the processor system can calculate all the above-mentioned values. Optionally excitation on the primary side is possible with free curves or PWM signals. Moreover, Additional software packages are available for individual measuring operations such as DC bias offset, pulse-width modulation signals, free curves and higher harmonics.
