PROBLEM TO BE SOLVED: To provide a vibration measurement system capable of efficiently carrying out measurement of the vibration phase of a rotor of a rotating body. SOLUTION: The system includes a vibration sensor for detecting a rotational vibration deformation of the rotor for outputting a vibration wave signal, a rotation detector for detecting the rotation of the rotor to output a rotational pulse signal, a vibration phase detecting device which detects the imbalance components of the rotor, on the basis of the vibration wave signal detected by the vibration sensor and the rotational pulse signal detected by the rotation detector; and a radio transmission unit which transmits the rotational pulse signal detected by the rotation detector to the vibration phase detection device through radio communication. The vibration phase detecting device obtains vibration phase, by correcting the transmission delay in the rotational pulse signal, from the rotation detector. COPYRIGHT: (C)2008,JPO&INPIT
