Which of the following examples relates to condition monitoring?

Condition monitoring involves the process of regularly checking and assessing the operational health of machinery to prevent failures and extend the life of equipment. Performing oil analysis is a perfect example of this practice. It provides valuable insights into the condition of the machine, as the analysis can reveal important information about the wear particles, contaminants, and the chemical composition of the oil.

Regular oil analysis allows for the identification of potential issues before they lead to equipment failure, enabling proactive maintenance decisions. This means that engineers can monitor the performance of the lubricant in its application, understand the condition of the machinery, and make informed predictions about when maintenance or repairs might be needed based on the condition of the oil and the machinery it lubricates.

In contrast, starting a backup generator, checking an overspend switch, and replacing an oil filter all involve actions taken in direct response to operational needs or routine maintenance tasks, rather than ongoing monitoring and assessment for the sake of condition-based maintenance strategies.
