Operating Principle
The sample is exposed to a defined magnetic field within a measuring coil. A magnetic flux is created inside the material. The required current is supplied by a power amplifier.
The current is measured by means of a temperature-stable and induction-free precision resistor (shunt) or by field coils.
Polarization is determined by measuring the induced voltage, and then conversion and integration by means of a 16 bit processor.
Parallel recording of H and J sizes in separate recording systems guarantees absolutely parallel measurement. Errors in measurement due to phase displacement are thereby avoided.
The processor calculates all the values
from the differentiated and integrated parameters.
Measuring coils
- SST sensor for "as delivered" slit strips, following IEC 60404-3
- C 510 sensor for punched parts and small cuts
- Measuring module for rings, stators and transformer cores
