FIELD: machine building.
SUBSTANCE: device for contactless blade vibration measurement has sensors (6, 7, 8, 9), signal recording unit (14) and measurement result processing unit (13), which are located in circumferential direction of rotor (3) equipped with rotating blades (10). Devices intended for determination of position of rotor and/or deformation of housing are provided. In addition, method of contactless blade vibration measurement is described.
EFFECT: action of radial rotor movements and housing deformations, the so called ovalisation on measurement data is eliminated by means of the present invention, and high resolution capability is provided under all conditions as per amplitude during vibration analysis.
