Imbalances on rotating machines are often the reason of troublemaking vibrations and noise. During imbalance, the primary axis of inertia or center of gravity of the revolving machine component is outside its axis of rotation. By adding or removing masses, the center of gravity or the principal axis of inertia can be erased so that both coincide with the axis of rotation. This process is called balancing. The machine component is then balanced and runs without vibration. Optional Software is available for Data Acquisition and Control Function.
