This paper reviews the evolution and current state of the maintenance art. It presents a key measurement philosophy that results from the use of Condition Based Maintenance (CBM) as a fundamental investigative precept, and how this approach impacts degradation and failure measurement and prediction accuracy. It then examines of how this measurement approach is applied in sensing and correlating pump stressors with regard to degradation rate and time to equipment failure. The specifics are examined on how this approach is currently being applied in the Laboratory to cavitation and vibration phenomena in a centrifugal pump.
