What is predictive maintenance?
Fixing things just before they break — driven by condition data, not the calendar.
Predictive maintenance (PdM) uses condition data — vibration, temperature, current, ultrasonics — to detect developing faults and predict when an asset will need attention, so work happens at exactly the right time.
Preventive maintenance acts on a schedule whether the asset needs it or not. Predictive maintenance acts on evidence: intervene early when a real fault is developing, leave healthy assets alone.
