Analyzing machine vibration as a means of monitoring healthy operation and diagnosis of emerging problems is a relatively mature specialization, long practiced on turbines and motor-pump trains. Condition Monitoring for the factory today is generally implemented by a skilled practitioner equipped with a handheld data-logger, collecting and processing signals from a tethered vibration sensor during a periodically scheduled, route-based maintenance program.

The analysis of machine states in CBM can be accomplished using various methods. The probably most common methods are analysis in the time domain, analysis in the frequency domain, and a mix of the two. This tip reviews high level methods for using each of these approaches to determining machine health.
