Condition Monitoring Expert Tip #1 by Mobius Institute

How do you decide which condition monitoring technologies to use?
There are many condition monitoring technologies that we could employ. And within each technology there are sub-technologies. For example, within vibration analysis we can use high frequency analysis, spectrum analysis, time waveform analysis and phase analysis. Within each sub technology there are settings we must select. For example, we must set the frequency range when collecting spectra. But which technologies should we use? Which settings are correct? The best way to make those decisions is by understanding the failure modes of the equipment.
If you understand what leads to failure, and what is likely to fail, you can select the most appropriate technologies and settings. You may argue that that is an obvious statement to make. You are probably not using vibration analysis on your steam traps… But after 30 years of experience in vibration analysis, it is common to see that fault conditions a totally missed because of the misapplication the technology.
It is not necessary to perform a full RCM (reliability centered maintenance) or FMEA (failure modes effects analysis) to make this determination. A so-called “accelerated RCM” is sufficient to ensure that you make the right decisions.
