Paper Abstract

In order to ensure the operating security of pressure containers, the welded joint angularity and stagger joint must be checked. The object of our studying in this paper is the instrument we have developed for measuring the welded joint angularity and stagger joint based on the capacitive displacement sensor. Though the analyses of error factors in design, manufacture and operating, such as principle error, the capacitive sensor error, the manufacture error of mechanical scales, the assemble error, the operating error. A method of reducing errors and increasing precision of the products has been posed, and has found ready application in practice.
