PEC - Pulsed Eddy Current - electromagnetic inspection technology

Pulsed Eddy Current (PEC) is an electromagnetic inspection technique used to detect wall loss on ferromagnetic structures such as carbon steel and cast iron. It provides a relative volumetric measurement converted into an averaged thickness measurement based on the calibration area. To generate and capture PEC, first, a magnetic field is created by an electrical current in the coils of the probe. It penetrates through the cladding, any non-conductive insulation (concrete, silicate, insulation with weather jacket or marine growth) and stabilizes in the component thickness.
