Magnetostrictive test system

laboratoryfor electrical networksautomatic

Overview

A magnetostrictive tester measures the length change (magnetostriction coefficient λ) of ferromagnetic materials under an alternating magnetic field and records the relationship between magnetic field intensity and material deformation for study, teaching and research purposes.

Product Features

• Real-time visualization: instrument display plots magnetic field intensity versus magnetostriction in real time for immediate observation.
• Complete data recording: the system logs all experimental data throughout the test sequence for traceability and analysis.
• Clear teaching demonstration: graphical displays support classroom and laboratory demonstrations of magnetostriction behavior.
• Reduced human error: automated data capture removes transcription errors associated with manual recording.
