CM-393 is a system to monitor vibration of machinery, etc., and it can quickly detect abnormal vibration condition and provide alarm signal.
It is ideal for continuous vibration monitoring at power plants or production facilities.
Either of 2 measurement modes, acceleration or displacement, can be easily selected on the front panel.
It is possible to set alarm trigger level at any desired displacement between 10 to 990μp-p(at 10μp-p step). Also, alarm delay time is available for up to 30sec to prevent false alarming.
