spectrum of the vibration signal, un­ balance is seen as an increase in the vibration at the frequency of rotation. The vibration due to the unbalance is measured by means of an acceler-ometer mounted on the bearing hous­ ing, see Fig. 5. The vibration signal is passed through a filter tuned to the rotational frequency of the rotor, so
