常を検知する回転機械の監視装置。 A rotation speed measuring device directly connected to a rotating machine to be monitored, a control device for controlling a drive source that drives the rotating machine, and inputting an output signal from the rotation speed measuring device and an output signal from the control device. and a timing circuit that measures the time from the time when the stop signal of the drive source is received until the signal reaches zero or a preset signal level, and automatically measures the elapsed time from the stop of the drive source of the rotating machine to the stop of rotation. A monitoring device for rotating machinery that detects abnormalities in bearings and seals based on the length of elapsed time.
