An apparatus for non-contact blade vibration measurement having sensors (6, 7, 8, 9) which are arranged around the circumference of a rotor (3) which is formed with rotor blades (10), having a signal detection unit (14) and having an evaluation unit (13), is characterized in that devices are provided to determine the rotor position and/or the housing deformation. Furthermore, a method is specified for non-contact blade vibration measurement. This avoids the technical problems of the prior art, and provides an improved apparatus and an improved method for non-contact blade vibration measurement. In particular, the attainment according to the invention eliminates the effect of rotor radial movements and housing deformations, i.e., oval deformations, on the measurement data, thereby ensuring high amplitude resolution for the vibration analysis under all conditions.

Dispositif de mesure sans contact de la vibration d'aubes mobiles, comprenant des capteurs (6, 7, 8, 9) disposés autour de la circonférence d'un rotor (3) pourvu d'aubes mobiles (10), une unité (14) de détection de signaux et une unité d'interprétation (13). Selon l'invention, des moyens sont prévus pour déterminer la position du rotor et/ou la déformation du carter. L'invention concerne en outre un procédé de mesure sans contact de la vibration d'aubes mobiles. On évite ainsi les problèmes techniques de l'art antérieur et on fournit un dispositif amélioré et un procédé amélioré de mesure sans contact de la vibration d'aubes mobiles. La solution selon l'invention élimine notamment l'influence, sur les données de mesures, des mouvements radiaux du rotor et des déformations du carter, c'est-à-dire de l'ovalisation. Elle garantit ainsi dans toutes les conditions une résolution d'amplitude élevée lors de l'analyse des vibrations.
