Measuring Unit MPG 100 D

Product catalog summary

Overview: The document provides detailed information on the determination of magnetic properties of electrical steel and other soft magnetic materials using advanced measuring technology. It highlights the capabilities of the Measuring Unit MPG 100 D by Dr. Brockhaus Messtechnik GmbH & Co. KG.

Specifications: The system supports parallel connection of up to 12 measuring coil systems and fully digitized data documentation. It is versatile, easy to operate, and includes automatic coil changeover. The system is compliant with IEC 60404 and ISO ASTM standards for measurements using Epstein frames and sheet measuring coils.

Measuring Categories: The system measures specific hysteresis loss, maximum and effective polarization, maximum and effective field strength, remanence, coercive field strength, permeability, specific apparent power, and more. It also provides hysteresis display and J(H) values for graphic display.

Operating Principle: The system uses a measuring coil to expose material samples to a defined magnetic field, creating magnetic flux in the steel sheet. The current is measured using a precision resistor or field coils. The system ensures simultaneous measurement of H and J values, eliminating phase displacement errors.

Measuring Coil Systems: The document describes various measuring coil systems, including Epstein frames for different frequencies, C 510 measuring coils for punched parts, and modules for rings and transformer cores. Custom-made frames and coils are also available.

Operation and Evaluation: The MPG Expert software facilitates simple operation and parameterization of measuring processes under Windows. The system offers repeatability of 0.2% and comparability of results according to IEC 60404 standards.

Technical Data: The system operates with a maximum current of ±40 A and voltage of ±110 V, with coil connectors ranging from 3 to 12. It supports measuring frequencies from 3 Hz to 10 kHz and requires a power supply of 3 x 220 – 440 V AC, 50/60 Hz.

Additional Systems: Other measuring systems include the C 510 for electrical steel, EBA for inline measurements, and Franklin Tester for surface resistance.

Measuring Unit MPG 100 D Operating principle In a measuring coil a material sample is exposed to a defined magnetic field and magnetic flux is created in the steel sheet. The electric current required is supplied by a power amplifier. The current is measured by means of a temperature-stable, induction-free precision resistor (shunt) or via field coils. Determination of the polarization by measurement of the induced voltage, and then conversion and integration by means of a 16-bit processor. Parallel recording of the H and J values with separate recording systems guarantees absolutely simultaneous...
