<
Vibration analysis is the ability to collect vibration data from machinery, interpret the data to establish the "health" or working condition of that piece of equipment. Below are some examples of collected data and there interpretations.

This spectrum shows a bearing on a fan that is failing.
Not only can we find and predict bearing failures, we can also determine where the problem is within the bearing. In this case the most wear is on the outer race as indicated by the BPFO harmonics.
