A brief introduction to machine vibration analysis techniques

One other vibration analysis technique for identifying the root cause of the vibration is called synchronous time averaging (STA). It uses a rotational signal from a roll, pump shaft, pressure screen rotor, or press felt trade line (called a trigger) to synchronize the raw wave form based on position of the rotating object.
