ABSTRACT:
A monitoring system for representing vibration conditions of a multiplicity of blades on a rotating disc in a turbomachine includes at least one sensor which is associated with the disc and which is connected to a pulse generator that delivers sensor pulses which respectively mark an instant at which a blade passes the sensor, a mark pick-up which always delivers a mark pulse when the disc is in a certain zero position, and an analysis device. The latter has an allocation module which takes account of the mark pulses and associates each sensor pulse with the blade which has caused it when passing a sensor. The allocation module calculates vibration data from the associated sensor pulses, which characterize the vibration conditions of the blade. A memory module has access to a working memory to which the vibration data are supplied and the memory module stores the vibration data in the working memory. In addition, the monitoring system has a representation device through the use of which the vibration data can be called up from the working memory and can be represented on at least one representation medium.
