magnetic fieldmagnetic propertiesEpstein

• Determination of the magnetic properties of electrical steel in all common quality grades, thicknesses and geometries and of other soft magnetic materials • Quality control of strip steel, punched parts, stators, transformer or ring cores • User commands and control via PC under Windows • Versatile • Easy to operate • Fully digitalized measuring unit • Three coil connectors for different measuring requirements • Module for the measurement of rings, ring strip cores, stacked punched parts etc. • Possibility to extend the modules to include Epstein measurements • MPG Expert software for measurement, presentation and integration into QM systems 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
