A survey conducted by Preditec-IRM during the First Spanish Forum on Preventive/Predictive Maintenance and Reliability, based on a sample of 200 companies using predictive maintenance, shows that of the five most widely used techniques that should be employed in a proper PdM program (vibration, ultrasonics, thermography, oil analysis, MCA, and sensory inspection), only vibration is used in a large percentage of cases, while the other techniques account for a small percentage.
Best practices indicate that, in order to identify all possible failure modes that an asset may exhibit and thus anticipate total failure, it is necessary to use all currently available techniques, among which those mentioned above are the most widely applied in PdM.
