Gearbox defects can be identified with a quite high accuracy using vibration analysis. This is because the fact the most common defect frequencies are the fundamental Gear Mesh Frequency (GMF) and its harmonics (such 2x GMF, 3x GMF) which can easily detected.

With process control systems, it’s simple (and smart) to incorporate vibration data into an existing monitoring program. Either loop-powered 4-20 mA sensors, which output a direct 4-20 mA signal, or IEPE sensors, which output dynamic data that can be converted into an acceptable process signal, can be used..

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.
