Abstract
PURPOSE:To enable proper monitoring of vibration and processing after the monitoring, by enabling direct visual judgement of whether the present vibration levels of plural meausred points have changed to a safe side or a dengerous side. CONSTITUTION:The vibration of bearings 5 of turbine rotors 1, 2, 3 and an electric generator rotor 4 is detected by vibration sensors 7-1-7-8. The outputs of the sensors are applied to an analogue input circuit 10 through an amplifier 9. At the same time, multichannel analogue signals are applied from the amplifier 9 to the analogue input circuit 10 which sequentially transmits the signals to an A/D converter 11. A calculation and comparison circuit 100 performs calculation on overall vibration signals supplied from the converter 11. The overall vibration signals are then supplied to a calculator 200, the outputs of which are indicated on a display unit 14 through a controller 13 together with vibration ratios stored in a memory 302.
