Machine Health Basics For The OEM Design Engineer
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.
