Start with a clear question
Condition monitoring is useful when it answers a maintenance decision: Is the asset deteriorating? Is immediate inspection necessary? Can work be planned for the next controlled stoppage? Define the critical machine, fault mechanisms and action owner before collecting large amounts of data.
Collect comparable measurements
Vibration, oil condition, temperature and operating parameters can reveal different symptoms. Record load, speed, sampling position, instrument settings and process conditions. Comparing readings taken under very different loads can create apparent deterioration that is caused by the process, not the machine.
Use trends rather than isolated numbers
A stable baseline makes gradual changes easier to identify. A rapid change, even below a generic alert threshold, can warrant attention. Conversely, a single high reading should prompt verification of the instrument, mounting, units and operating state before a major intervention is ordered.
Connect alerts to inspections
A monitoring program fails when reports are not converted into decisions. Define the escalation route, inspection deadline, ownership and acceptance checks. Maintain a record of confirmed faults and false positives so thresholds and methods can improve over time.
Respect safety boundaries
Monitoring results are advisory information, not authorization to operate unsafe equipment. Protective trips, statutory inspections and operational limits remain in force. Consult qualified personnel and equipment requirements before changing any safety-related operating decision.
