Monitor fatigue turbine blades.

A MONITOR FOR FATIGUE VIBRATORY ONLINE MEASURED EWL OFFSET an object such as a blade of a turbine rotor that generates a displacement signal CAUSED BY THE VICINITY OF SENSORS AND CALCULATING FATIGUE CUMULATIVE IN THE OBJECT IN RELIANCE ON POSTING OF THE SIGNAL. The signals are digitized and processed, BY MEANS OF A HILBERT TRANSFORMATION TO DETECT THE DEVELOPMENT AND FREQUENCY SURGE OF AMPLITUDE OFFSET. The amplitude and frequency combined with steady state TENSIONS ON FATIGUE object to determine which accumulates vibration displacement PROCESSING AND CONSTANT CHANGE IN THE STATE OF TENSION.
