PURPOSE:To eliminate the mechanical wear and the deterioration by giving a constant magnetic field to a detecting coil by a magnet, and also, holding a magnetic sphere centering around a container at the time of non-acceleration, and displacing the magnetic sphere and a ferromagnetic fluid at the time of acceleration. CONSTITUTION:Magnets 5, the inverse of 5, 5A and the inverse of 5A hold the magnetic sphere 3 centering around a hermetic container 1 by the action of magnetic force, and also, give the constant magnetic field to detecting coils 4, the inverse of 4, 4A and the inverse of 4A, and provided concentrically, with them, respectively. At the time of operation, a G sensor gives the constant magnetic field to the detecting coil by the magnet, detects differentially the variation of the magnetic reluctance of a magnetic circuit generated by the displacement of the magnetic sphere and the ferromagnetic fluid generated under the acceleration action being parallel onto the center axis, by the detecting coil, and detects the direction and magnitude of its acceleration. |
