Abstract: A monitoring system and method monitor changes in clearance distances between a sensor and a rotating component of a machine. Imbalance and/or wear in the machine is identified based on the changes in the clearance distances. The system and method optionally both measure the clearance distances and a rotating speed of the rotating component of the machine with the same sensor. In order to identify imbalance in the machine, a spectral energy of the machine can be calculated based on the changes in the clearance distances, and the imbalance in the machine can be identified based on the spectral energy. The system and method can determine a trigger speed of the machine that is associated with the wear in the machine based on the changes in the clearance distance. A remaining useful life of the machine can be estimated based on changes in the trigger speed.

Abstract: A system for monitoring health of a rotor is presented. The system includes a processing subsystem that generates a plurality of frequency peak values corresponding to two or more respective windows of signals by iteratively shifting the two or more respective windows of signals along delta times of arrival signals corresponding to a blade in the rotor, determines one or more resonant-frequency rotor speeds ranges of the blade by identifying rotor speeds corresponding to a subset of the plurality of frequency peak values, and monitors the blade to determine a presence of one or more defects in the blade during the resonant-frequency rotor speeds regions.
