Predictive maintenance is defined in EN 13306:2010 as maintenance that follows a prediction obtained from the repeated analysis of known characteristics and the evaluation of the significant parameters of the degradation of the element. Therefore, it allows to establish interventions when certain alarms are exceeded in the periodic evolution of certain control parameters.

These control parameters are defined according to each technology, the main ones being:

The choice of one technology or another will depend on the failure modes to be detected based on the corrective actions proposed by the previous failure analysis. Each technology requires an implementation process, where typically each of the parameters for its correct acquisition and alarms is defined. This process requires knowledge of the technology itself, but fundamentally of the type of engine to be subjected to this type of maintenance.

Therefore, we will obtain a series of parameters required for the implementation of each of these variables.

Based on these variables, a database will be created for the processing and analysis of the information subject to monitoring.
