APPARATUS AND METHOD FOR PROCESSING VIBRATIONAL INPUT OF ROTATING MACHINE, AND VIBRATION DIAGNOSIS DEVICE

摘要

PROBLEM TO BE SOLVED: To match the level of a plurality of different detection signals detected with a detector of a diagnosis device of a rotating machine to a specific level and process it as digital data.;SOLUTION: The diagnosis device has a detection part 21 provided with a plurality of different detectors 25a and 25b detecting the vibration of the rotating machine as an analog signal, a detection processor 22 provided with a level conversion board 33a for receiving analog signals from the detectors 25a and 25b, switching the gain and converting the analog signals to each specific level, an ADC board 36a for converting the analog signals whose level is converted by the level conversion board 33a to a digital signal and a CPU board 40 for processing the digital signal, and a diagnosis part 23 provided with a host computer 41 and an display 42 for calculating the digital signal processed by the detection processor 22 and diagnosing the vibration.;COPYRIGHT: (C)2006,JPO&NCIPI
