<p>PROBLEM TO BE SOLVED: To provide a bearing vibration monitoring device capable of sounding an alarm by a simple operation without overlooking abnormality of vibration of a bearing of a rotating machine, and thereby reducing the load of an operator. SOLUTION: This device has a constitution equipped with a deviation operation means 2g for operating deviation between output data of a data processing means 2a for processing data inputted from detectors 1a-1h for detecting the vibration of the bearing of the rotating machine and data read out from a readout means 2d, a second input processing means 2i for processing requirement from a second input device 3c where an alarm value is inputted by the operator, a manual alarm value setting means 2h for inputting the operation result from the deviation operation means 2g and setting the alarm value set by the second input processing means 2i based on the data, a fixed alarm value setting means 2k for monitoring the data inputted by the data processing means 2a by the alarm of an absolute value, and an alarm output processing means 2j for requiring alarm output to an alarm output device 4, when the data exceeds the alarm value set by the fixed alarm value setting means 2k or exceeds the alarm value set by the manual alarm value setting means 2h.</p> |
