A brief introduction to machine vibration analysis

Very low frequency vibration normally comes from process control systems and is better analyzed using the mill DCS or a process database such as PI or Aspen. One other vibration analysis technique for identifying the root cause of the vibration is called synchronous time averaging (STA).
