Abstract
A method is provided for determining and for predicting the present and future condition of a machine having at least one rotative element. The method includes an initial step of storing in memory a predetermined logic routine and at least one predetermined key frequency of the at least one rotative element of the machine. The machine is operated in a predetermined operational state and, during operation, the mechanical motion of the at least one rotative element is sensed by at least one sensor. The sensed mechanical motion of the at least one rotative element is converted into a corresponding electrical signal, and the predetermined operational state of the machine is correlated with a corresponding electrical signal. The corresponding electrical signal is inputted into corresponding vibration data by utilizing the predetermined logic routine. Then, the corresponding vibration data is compared with the at least one predetermined key frequency to predict the present and future condition of the machine. A control signal is transmitted to the machine, in order to control the machine, in response to the present condition and the predicted future condition of the machine.
