Eddy-Current Inspection Instrument

The eddy current instrument operates based on the principle of electromagnetic induction. It generates an alternating magnetic field through a probe. When the probe is brought close to a conductive material, eddy currents are induced in the material. Variations in these eddy currents reflect characteristics such as electrical conductivity, defects, or thickness of the material. It is used to detect surface cracks, corrosion, and coating thickness in metals, and is applied in non-destructive testing in industries such as aerospace and automotive manufacturing.
Selection
When selecting an eddy current instrument, considerations should include the type of material to be tested, the range of electrical conductivity, and thickness. The frequency and probe sensitivity should be determined based on the size of defects. Environmental factors influence the choice of probe type. The portability of operation and data analysis capabilities should meet on-site requirements. Refer to industry standards to verify the suitability of the instrument.
