ABSTRACT:
There is dislosed a vibration telemetering system capable of measuring adverse vibrations of installations or equipment in a plant such as a nuclear power plant. The system includes a vibrometer which measures the vibrations in a non-contacting fashion. The direction at which the vibrometer faces is adjusted by an angle adjusting mechanism which is mounted on a travelling unit running along a predetermined inspection route in the plant. A measured signal from the vibrometer is transmitted to a remote control room through a communication system and is used for evaluating whether or not the state of the plant is normal. The remote control room can control the travelling unit and the angle adjusting mechanism through the communication system in order to monitor the vibrations of a plurality of places along the predetermined inspection route.
