Abstract
The present invention is for a system ( ) or method for conditioned based monitoring of a bearing assembly. The system ( ) comprises a sensor ( ) placed in proximity to a bearing assembly ( ). The sensor ( ) generates a signal indicative of the amplitude and frequency of the vibrational movement of the bearing assembly. A process ( ) in communication with the sensor ( ) receives the signal from the sensor ( ) and generates spectral data representative of the bearing vibrational movement. A database ( ) comprises data representative of an amplitude threshold, for at least one predetermined frequency, characteristic of a bearing fault. The processor ( ) compares the spectral data to the amplitude threshold and generates a signal indication of the bearing assembly.
