A device for measuring a gap between two objects located remotely from a user includes a base, a slider and a wedge. The slider is slidably received in the base and the wedge is attached to the slider and also slidably received in the base. A push-pull cable has a proximal end connected to the slider. The wedge is inclined at a predetermined angle and slides along an angled surface of the base such that a force applied to a distal end of the cable causes an upper surface of the wedge to move vertically forcing the wedge and the base into respective contact with the two objects forming the gap. By measuring the distance that the push-pull cable slides, the vertical distance traveled by the wedge and thus a measurement of the gap may be determined.

Gap measuring device

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.
