Abstract

Un sistema explorador o analizador controlado por computadora, para inspeccionar cilindros grandes, tales como anillos retenedores de generador. El sistema destaca un explorador de baja holgura, el cual reparte en forma simultánea, corriente parásita y detectores de prueba ultrasónica, necesarios para desarrollar la inspección del anillo retenedor.A computer controlled scanner or analyzer system for inspecting large cylinders, such as generator retaining rings. The system features a low clearance scanner, which simultaneously distributes eddy current and ultrasonic test detectors, necessary to perform the retaining ring inspection.
