PURPOSE:To provide a vibration detecting system monitoring a vibrating condition of a magnet without any contact and an abnormal condition diagnosing system, which detects an notifies of an abnormal condition on the basis of the vibration information, for reliability of the magnet to be maintained in a vibration environment. CONSTITUTION:The vibration detector and the abnormal condition diagnosing device are constructed in such a way as comprising a magnet device consisting of a magnet 13, a conductive container 2 storing the magnet 13, a supporting member 5, and the like, a magnetic flux detecting element 6, which is arranged inside or outside the conductive container 2 sroring the magnet 13 and detects magnetic flux, an inputting device 7 inputting a magnetic flux detecting signal, a sensitivity matrix 9, a converting 8 converting the magnetic flux detecting signal into vibration information by making reference to the sensitivity matrix 9, an indicator 10 indicating the vibration information and the like, a comparator 11 comparing the inside/outside magnetic flux signal or the vibration information, a warning device 12 giving an alarm when the compared result exceeds a predetermined value, and a diagnosing unit 14 assuming an abnormal condition generating position and the like. |
