Abstract
A method for monitoring machine operation for various machine speed and loads includes measuring vibration information at a sensor associated with a machine and an associated machine speed. The machine is a rotating machine. The method includes performing an operational frequency analysis of the vibration information and comparing results from the operational frequency analysis with a vibration signature for the machine. The vibration signature is for a machine speed that matches the machine speed of the measured vibration information. The vibration signature is one of several vibration signatures for the machine where each is for a different machine speed. The method includes identifying a potential failure mode based on a frequency range where the frequency analysis of the measured vibration information exceeds, by a threshold amount, the vibration signature of the plurality of vibration signatures that matches the machine speed, and transmitting an alert comprising the identified potential failure mode.
