Abstract
A probeincludes exciter unitsarranged in an array and detector unitsand, also arranged in arrays, with the arrays positioned proximal to and in the shape of the exterior circumference of an individual boiler tube. The detector unitsare 'absolute' coil detectors which are used to detect and quantify general wall loss, for example, resulting from steam impingement erosion. The detectorsare differential, axial pairs which are used for detecting pits in the boiler tubers. The exciter units and detector units are mounted in a stainless steel housingof the probe. The housingis shaped to closely match the contour of the boiler tube. The probe can be moved along the boiler tubes by hand to inspect the flame side of boiler tubes, one at a time. Wheelsare provided to roll the probe along the boiler tubes.
