A vibration sensor includes a permanent cylindrical magnet, coil and two cylindrical springs, additional permanent cylindrical magnet attached to the main permanent cylindrical magnet with same pole, additional coil connected in series opposition to the main coil. Each of the coils is connected to differentiator, and two permanent cylindrical magnets are used as two cylindrical springs, the poles of those are directed to the same poles of the main permanent cylindrical magnets. Two flux-gate meters are used, those are placed between the coils at opposite sides of the permanent cylindrical magnets, and the output windings of the flux-gate meters are connected in series opposition. |
