Abstract

A predictive vibration monitoring system for a machine includes amicrocontroller (20) and a machine to be monitored (10).
The machine to be monitored (10) includes at least one rotative element. At least one sensor (12) is operatively connected to the machine (10). The at least one sensor (12) is operable to convert mechanical motion generated by the at least one rotative element into a corresponding electrical signal. The at least one sensor (12) inputs the corresponding electrical signal to the microcontroller (20). A
communication means (22) is disposed between the microcontroller (20) and the monitored machine (10).
The communication means (22) enables the microcontroller (20) to correlate a predetermined operational state of the monitored machine (10) with a corresponding electrical signal generated by the at least one sensor (12). A memory means (38) communicates with the microcontroller (20) and stores a predetermined logic routine, at least one corresponding electrical signal and at least one predetermined key frequency of the at least one rotative element of the machine to be monitored (10). The microcontroller (20) utilizes the predetermined logic routine to process the corresponding electrical signal into corresponding vibration data of the monitored machine (10). The microcontroller (20) compares the corresponding vibration data with the at least one predetermined key frequency to predict the present and future condition of the at least one rotative element.
