Abstract
A characterized inner electrode for a capacitive fuel-gauging probe comprises several discrete tubular sections of different diameters which are joined together end-to-end by metal coupling pieces. One or more of the tubular sections has two regions of different diameters that are continuous with one another, the smaller diameter region being formed by swaging down from the larger diameter region. The coupling piece has two shoulders to which the ends of the tubular sections are electron-beam welded. The coupling piece also has respective annular recesses into which a low viscosity adhesive is introduced via overlying apertures in the tubular sections after welding, so as to form an adhesive joint between the coupling piece and the tubular sections. The ends of the coupling piece are a close fit within the tubular sections and extend into them by a distance at least twice the diameter of the coupling piece.
