EBA Inline Measuring System

Product catalog summary

Overview: The document provides a detailed description of the EBA Inline Measuring System developed by Dr. Brockhaus Messtechnik GmbH & Co. KG for monitoring and documenting the soft magnetic properties of electrical steel. It emphasizes continuous inline quality control and the measurement of specific hysteresis loss and peak induction.

Key Features:

Simultaneous data capture for magnetic field strength (H) and magnetic polarization (J).
High reproducibility and measuring accuracy with programme-controlled operation.
Integration with EBA Expert software for measurement, display, and quality management system (QM) integration.

Measuring Categories:

Specific hysteresis loss
Maximum polarization
Maximum field strength
Remanence
Coercive field strength
Permeability

Technical Specifications:

Measuring frequencies: 50 or 60 Hz, up to 400 Hz possible.
Repeatability better than 0.5%.
Comparability of results statistically ± 2% against Epstein measurement.
Maximum field strength: 5,000 A/m.
Maximum speed: 300 m/min.
Maximum strip width: 1,300 mm.
Power supply: 3 x 220-440 V AC, 50/60 Hz.

Operating Principle: The system includes a measuring and processing unit with a double-yoke system and necessary coils. It is installed in the production line, guiding the material through the unit. The system can process digital signals for tracking material during production and incorporates values for polarization and field to calculate hysteresis loss.

Components:

Power amplifier up to 4 kW.
16-bit microprocessor measuring unit and PC for process visualization.
Optically separated digital inputs for process signals, with analogue outputs and inputs.
Serial interfaces for QM system integration.
Industrial-grade 19"-TFT monitor and keyboard.

Additional Information: The document also mentions other product divisions such as measuring technology for hard magnetic materials, magnetizing technology, and services offered by the company.

EBA Inline Measuring System Operating principle The measuring system consists of a measuring and processing unit together with a double-yoke system with all the required coils (exciting coil, secondary coil, tangential field coil). The double-yoke system is installed in the production line. The material to be measured is guided through this unit. In order to assign the measured and documented values clearly to one electrical steel coil the measuring system is able to administrate material identification data. Digital signals for the start and end of the measurement can be processed from the measuring...
