What seems like a “great idea” at the moment can often lead to regret and unwanted consequences later. This is true when it comes to equipment reliability and condition monitoring. What “great ideas” can a facility have today that can lead to unwanted reliability consequences later? Unfortunately, the choices are many!
Determination of condition monitoring intervals can be one of those “great ideas” that is regretted later.
It is possible to apply condition monitoring more often than is actually required to detect conditional changes in equipment, resulting in extra expenses being incurred. Conversely, it is possible to monitor equipment too infrequently for important conditional changes to be noticed on time and failures to occur. It can seem like a great idea to base condition monitoring frequencies upon arbitrary intervals, available manpower, or some standard sampling frequency (such as 30, 60, 90, or 180 days.) Each of these could prove to be an unfortunate decision taken on behalf of your reliability efforts. Make sure your condition monitoring frequencies are based upon the P-F interval. The equipment will usually let you know how often condition monitoring technologies should be applied and the P-F interval is a measurement of that. The appropriate sampling frequency can be determined with some effort and will ensure that you have no reliability regrets later.
