Our magnetic induction testing methods.

In the field of electromagnetic testing technology, we specialize in the following methods:

Eddy current testing (ET)

A fast and highly sensitive method for surface and near-surface inspection of electrically conductive materials. Ideally suited for detecting cracks, pores, inclusions, or material changes at high testing speeds – including inline applications.

Contact-free and usable without coupling agents.

Ideal for high cycle rates and automated production lines.

Detection of near-surface defects down to the millimeter range.

Remote field testing (RFT)

This method is particularly suitable for volumetric testing of ferromagnetic materials such as pipes or container walls. The sensor technology enables uniform detection of internal and external defects – even with one-sided access.

Testing possible through thick-walled materials.

Particularly well-suited for inspections of pipelines in installed condition.

High defect sensitivity for internal and external flaws.

Harmonic analysis of eddy current signals

An advanced method for material characterization and microstructure analysis. By analyzing higher harmonics of eddy current signals, microscopic material differences can be precisely detected – such as hardness gradients, tempered zones, or phase transformations.

Detection of the finest microstructural changes without metallographic cross-sections.

Process monitoring, e.g., during heat treatments and hardening processes.

Real-time classification of material conditions.
