Proactive Maintenance Diagnostics

Proactive maintenance work comprises routine tasks that include preventative work such as changing the belts on a conveyor at a regular interval and predictive work such as vibration analysis performed at a regular frequency. In some cases, the performance of proactive maintenance causes equipment failures. For example, in instruments such as pressure transmitters, the proactive work of verifying the calibration of the transmitter may cause instrument errors if performed too frequently. If these instrument errors are not corrected frequently, they may result in drift-induced errors. The errors due to proactive work that is performed more frequently than required are called maintenance-induced errors.

In Industrial Data Diagnostics, the Reactive vs Proactive Maintenance graph helps you identify equipment that are being over-maintained and under-maintained with respect to proactive maintenance. After identifying such equipment, you can eliminate unnecessary routine maintenance that does not add any value to the performance of assets in your organization. Optimizing the frequency of proactive maintenance results in increased asset reliability and reduced maintenance cost in your organization.
