ABSTRACT:
A system and methodology for continuous condition monitoring of rotating equipment. Employ adaptive signal processing techniques to determine the RPM of a rotating machine from time-based vibration data. RPM is determined based upon the input of a digitized time-based sample sequence of vibration data acquired directly from a vibration transducer for on-line real-time measurement of the machine RPM. Once RPM is determined, online vibration analysis for a given RPM or set of RPMs may be performed. The present invention extracts characteristic vibration features from vibration data and uses these extracted values to provide condition detection and diagnoses of machine faults.
