Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an apparatus and method for measuring relative concentricity deviations in a confined space between two circumferential elements, such as a turbine rotor and a turbine diaphragm.SOLUTION: The apparatus includes a housing 12, and a sensor 14 coupled with the housing 12 that measures a distance from the housing 12 to one of the two circumferential elements. An axial spring plunger 16 is connected to the housing 12, and a radial spring plunger 18 is connected to the housing 12 and arranged orthogonally to the axial spring plunger 16. The apparatus also includes a sliding or rolling surface on a side of the housing 12 opposite from one of the axial spring plunger 16 and the radial spring plunger 18.SELECTED DRAWING: Figure 2 【課題】タービンロータとタービンダイヤフラムとの間のような２つの周方向要素間の限られた空間における相対的な同心度の偏差を測定する装置および方法を提供する。【解決手段】装置は、ハウジング１２と、ハウジング１２から２つの周方向要素の一方までの距離を測定する、ハウジング１２に連結されたセンサ１４とを含む。軸方向ばねプランジャ１６はハウジング１２に接続されており、径方向ばねプランジャ１８はハウジング１２に接続され、かつ軸方向ばねプランジャ１６に直交して配置されている。装置はまた、軸方向ばねプランジャ１６および径方向ばねプランジャ１８の一方から反対側のハウジング１２の側面に、摺動面または転動面を含む。【選択図】図２
