MAGNATEST D
Magneto-inductive testing of metallic components for material properties
Processor-controlled compact unit with maximum performance. The MAGNATEST D is a powerful system for nondestructive magneto-inductive testing of metallic components. Differences in magnetic and electrical material properties can be reliably detected – from alloy composition and heat treatment to microstructure, strength, hardness, and case hardness.
Testing is performed as standard in single-coil absolute mode without the need for a reference coil. The impressed excitation current ensures a constant magnetic field strength, while high excitation currents enable even small differences in material properties to be reliably detected. Depending on the application, single-frequency and multi-frequency testing as well as fundamental and harmonic analysis are available.
By combining different test frequencies and magnetizing field strengths, different material properties can be evaluated while minimizing interfering influences. Harmonic analysis provides additional information about the material condition and helps reduce effects caused by temperature fluctuations or incorrect positioning of the test part. This supports high repeatability and long-term stability of the test results.
From manual testing in the materials laboratory to fully automated quality control in production, the MAGNATEST D can be flexibly integrated into different testing processes and higher-level systems. Part statistics, histogram displays, and test data export support transparent documentation and evaluation of test results. A wide range of test coils and probes enables adaptation to different component geometries and testing tasks. For applications involving multiple test coils, the system can also be expanded with the MULTIPLEXER

Application notes
Structure and Crack Testing Axle Pivots with Eddy Current
Material mix-ups, hardening errors or cracks in axle pivots can compromise safety. Eddy current testing reliably detects critical defects.
Monitoring the Autofrettage Process of Injection Systems
Incorrect autofrettage can weaken high-pressure tubes. Eddy current testing reliably verifies material properties and process quality automatically.
Structure Testing of Cast Components
Microstructure or material deviations in cast components can affect safety and performance. Magneto-inductive testing reliably identifies variations.
Microstructure and crack testing on rotor shafts using eddy current
Microstructure deviations or cracks in rotor shafts can reduce electric motor reliability. Eddy current testing reliably detects defects during production.
