OmniScan MX ECA

OmniScan MX ECA fra Olympus kan bruges til inspektion af rør og komplekse geometrier. OmniScans databehandling og de fleksible prober med flere spoler gør det muligt at visualisere revnerne og bestemme deres nøjagtige placering ved hjælp af encoder. ECA er, populært sagt, for hvirvelstrøm hvad Phased Array er for ultralyd.

Beskrivelse

Den velkendte OmniScan med ECA (Eddy Current Array) kan visualisere indikationer direkte på skærmen. Data kan fremstilles så det ligner resultatet fra penetrant- eller magnetprøvning.
