Predictive Maintenance (PdM) is a maintenance strategy that monitors the condition of equipment during operation to predict when maintenance will be needed. Unlike time-based or reactive approaches, PdM leverages various data collection techniques—such as vibration analysis, thermal imaging, oil analysis, and acoustic monitoring—to detect potential failures early.

By identifying nascent issues, organizations can schedule maintenance before a breakdown occurs, minimizing downtime, reducing repair costs, extending asset life, and enhancing overall operational efficiency. This data-driven approach moves beyond traditional preventative maintenance, optimizing resource allocation and improving reliability.
