Operating principle
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.
