Abstract
A tool measures relative concentricity deviations in a confined space between two circumferential elements, such as a turbine rotor and a turbine diaphragm. The tool includes a housing, and a sensor coupled with the housing that measures a distance from the housing to one of the two circumferential elements. An axial spring plunger is connected to the housing, and a radial spring plunger is connected to the housing and arranged orthogonal to the axial spring plunger. The tool also includes a sliding or rolling surface on a side of the housing opposite from one of the axial spring plunger and the radial spring plunger.
