The present invention provides a system and method for monitoring an electrical signal appearing on a rotating machine shaft. The system comprises a probe assembly for placement against the rotating machine shaft that is in electrically conductive contact with the shaft. The probe assembly includes at least one circuit for receiving the electrical signal from the rotating machine shaft and producing various electrical signals that are read by a data processing system, which is coupled to the circuit. The data processing system determines from the electrical signal obtained from the circuit, the RMS AC voltage, DC voltage, peak voltage, and the RMS AC and DC current through two different resisters that are all appearing on the rotating machine shaft. The data processing system also performs Fast Fourier Transforms on the RMS voltage and current signals and produces a frequency spectrum over time.

System and method for measuring and analyzing electrical signals on the

The specification discloses a laser alignment head system for taking alignment data with respect to a pair of coupled shafts. Each alignment head includes a laser, a laser sensor for sensing a laser beam, an angle sensor for sensing the rotational orientation of the laser head, a computer and a transmitter for transmitting data from the laser head. The two laser heads are mounted on the two shafts in an opposing facing relationship with the laser beam of one head disposed on the laser sensor of the other head. As the shafts are rotated, the laser beam moves on the laser sensor and the laser sensor generates a position signal corresponding to such movement. Likewise, the angle sensor produces an angle signal corresponding to the rotational angle of the laser head as the shafts are rotated. The computer produces output data corresponding to the position signal and the rotational angle, and such data is transmitted to a receiver. An analyzer is interfaced with the receiver to receive the data and calculate misalignment information.
