The following is from the lab notes for the hands-on lab "CBM and Condition Monitoring – Process vis-a-vis Equipment Reliability" at PI World 2018, San Francisco, CA.  Lab manual and slides are attached.

 

Condition-based maintenance (CBM) is a strategy where you monitor the actual condition of an asset to decide what maintenance needs to be done – see wiki for a broader definition. This is in contrast to a break-fix strategy (reactive maintenance) and also calendar scheduled maintenance (clean and lube every 3 months, laser align every 6 months etc.  ) regardless of the condition of the asset and whether it was used or not.

 

The PI System CBM eBook titled A Guidebook to Implementing Condition-Based Maintenance (CBM) Using Real-time Data is here.

 

This lab provides hands-on exercises to illustrate how to execute CBM in your plant using process and condition monitoring data.

 

A popular approach is to use a layered implementation, i.e.

  • Usage-based Maintenance (UbM)
  • Condition-based Maintenance (CbM)
  • Predictive Maintenance (PdM)
