CONDITION MONITORING STRATEGY - A RISK-BASED INTERVAL SELECTION

Condition monitoring (CM) has been widely applied in most of the moder n process as well as manufacturing industries as a predictive maintena nce tool for incipient fault detection and trouble shooting but the in terval at which the measurements are to be taken to achieve the best r esults has not yet been rationally discussed. This paper suggests a me thod for designing condition monitoring measurement intervals for all types of machines, from commissioning to replacement, by considering v arious factors such as risk, interval availability, debugging, useful life and wear-out regions of the failure rate curve, as well as econom ic factors governing the replacement prospects of the machine.
