Online Condition Monitoring
Continuous or frequent sensor data for assets where change needs to be observed between manual inspections.
What this topic covers
Continuous or frequent sensor data for assets where change needs to be observed between manual inspections.
Core ideas
Online monitoring increases data frequency but also creates sensor, communications and data-quality dependencies.
Continuous data is most valuable when linked to clear failure modes and response rules.
More data does not automatically improve integrity if alarms are ignored or measurements are unreliable.
Program tradeoffs
Data must retain asset identity, timestamp, units and operating context to support reliable trend analysis.
What good evidence looks like
Anomalies and model predictions are decision support, not automatic proof of failure.
Lifecycle perspective
OT security should protect monitoring availability and integrity without interfering with safe operation.
