Although condition-based and predictive maintenance have some overlap, there are distinct differences between the goals of each strategy.
| Condition-Based Maintenance | Predictive Maintenance |
|---|---|
| Equipment maintenance that is performed when its present state has deviated from a pre-determined condition. | Proactive maintenance performed using sensor data and trends to predict future equipment failure. |
| Goal is to use data collected during monitoring to perform maintenance at the exact moment it is needed and before a critical failure. | Goal is to schedule maintenance at a future time when it is more convenient and will have minimal impact on production. |
| Uses visual inspections, instrument measurements, and sensor readings to monitor an equipment’s present state. | Uses machine learning algorithms, which makes readings and predictions more precise over time. |
| A simple approach that relies on human factors for its execution and success. | Does not rely on a single datapoint, it looks at all data trends in context with the operation. |
