Abstract: Condition Monitoring is an advanced and very useful tool of predictive maintenance techniques. It has made good progress in recent years in identifying many types of deterioration in plant machinery, so that pro-active maintenance can be performed, improving overall plant productivity. There is a wide variety of condition monitoring techniques currently in use for the diagnosis and prediction of machinery faults, but little attention has been paid to the occurrence and detection of vibration analysis of rotating equipments The application of computers and electronic measuring and detecting system has provided a new improvement for condition monitoring and has a particular relevance for plant engineers in utilities and service departments. It eliminates unnecessary opening of equipment with considerable savings in personnel resources.
