Abstract (en)

[origin: CA2673425A1] An apparatus for non-contacting blade oscillation measurement having sens ors (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 pro vided to determine the rotor position and/or the housing deformation. Furthe rmore, a method is specified for non-contacting blade oscillation measuremen t. This avoids the technical problems of the prior art and provides a better apparatus and a better method for non-contacting blade oscillation measurem ent. In particular, the solution according to the invention eliminates the e ffect of rotor radial movements and housing deformation, that is to say oval deformation, on the measurement data, in this way ensuring good amplitude r esolution for the oscillation analysis, in all conditions.
