Hystograph HG 200

Product catalog summary

Overview: The document provides detailed information on the measurement of hard magnetic materials using the Hystograph HG 200 system by Dr. Brockhaus Messtechnik GmbH & Co. KG. It outlines the specifications, procedures, and technical data related to the measurement system.

Specifications: The system is designed for measuring various hard magnetic materials such as AlNiCo, Ferrite, PtCo, SmCo, NdFeB, and plastic bonded materials. It operates with a constant flux alteration (dΦ/dt) and uses J-compensated surrounding coils, pole, or field coils. The system can measure at temperatures ranging from -45°C to 200°C and is fully computer-controlled.

Measuring Categories: The system measures remanence, coercive field strength, maximum energy product, maximum field strength, maximum polarization, and provides a hysteresis display.

Operating Principle: The measurement process follows IEC 60404-5 standards, ensuring high accuracy and reproducibility by avoiding interference from eddy currents and phase displacement. The system includes a measuring table, voltage supply unit, measuring electronics, electromagnet, and computer hardware with MAG Expert software.

Technical Data: The system features an electromagnet with heating poles, J-compensated coils, and potential coils. It supports various measuring systems like AC/DC Hystograph, XYZ Field Scanner, Fluxmeter, and Gaussmeter. The power supply ranges from 0 to ±125 V and 0 to ±25 A, with an optional 50 A. The maximum field strength varies from 1,200 to 3,200 kA/m depending on the air gap, which ranges from 0 to 80 mm.

Additional Features: The system includes interchangeable measuring poles and coils, with options for customized sizes. It also offers a temperature control unit for measurements at different temperatures. The software, MAG Expert, operates under Windows and integrates into QM systems.
