Rilevamento di corrosione

Corrosion detection using eddy current array technology offers major advantages over conventional eddy current inspection methods. Because each individual eddy current coil generates a unique electrical signal in relation to the structure below it, the coils can detect very small changes in material thickness, along with other parameters, and display these changes as a color-coded C-scan image. Imaging using eddy current array allows easy interpretation of the data generated from the probe coils. After it has been collected, the inspection data can be stored, transmitted, and analyzed.

Color palettes play a very important role in the imaging of eddy current array data. Color palettes determine how the data will be displayed. Color palettes are often linked to the amplitude of the eddy current signals; however, when required, color palettes can also be linked to the phase angle of the signals. Color palettes range from a gradual rainbow palette to a precise, two-color "go/no-go" palette. Black and white palettes are also often used.
