ABSTRACT:
An apparatus for measuring vibration in a article having a rotating member. A motion sensitive transducer produces a time domain analog signal in response to the vibration. An analog-to-digital data acquisition member samples the transducer signal and produces a time domain digital signal therefrom. A timing sensor is adapted to detect an instantaneous speed of the rotating member and preferably triggers the data acquisition member to begin sampling when the rotating member is rotating. A processor processes the time domain digital signal preferably by translation to a frequency domain digital signal and determination of the magnitude and phase of the frequency domain digital signal at a frequency associated with the instantaneous speed of the rotating member.
