Vibration measurement and analysis is the “Cornerstone of Predictive Maintenance” which stands in sharp contrast to the historical run-to-failure type of maintenance practice. Numerous studies have shown that on average, the cost to industry for maintenance will be reduced by more than 50% if a predictive maintenance program is used instead of run-to-failure.

After the vibration signatures are verified as to validity and the spectral peaks, the diagnosis of machine problems can begin. There are variety of machine problems and illustrates them with their typical vibration signatures.
