Abstract
Disclosed is an apparatus for measuring the deviation from a straight line of an elongated passage having opposing sides. The apparatus comprises a member sufficiently bendable and sufficiently large that it can pass through the passage in contact with both of the sides of the passage. Included is a means for measuring the amount that the member bends as it passes through the passage, means for moving the member through the passage between its opposing sides, and means to indicate, collect, and analyze the resultant electrical signals. The apparatus is most useful in measuring and locating deformations in the tubes of the steam generators of nuclear reactors.
