MOVEMENT DETECTOR FOR LOW GRAVITY CONDITIONS

摘要

The invention relates to a movement detector applicable to simultaneously measuring the axial and angular dynamic parameters of a mobile body under low gravity conditions The detector consists of an enclosure (1) filled with a mixture of magnetic liquid (6) and conducting non-magnetic particles (7) with a mass density higher than the mass density of the magnetic fluid, the non-magnetic particles (7) being positioned by two permanent magnets (2) and rotated in a rotating electromagnetic field generated by an adequate stator, the position thereof being converted into an electric signal by two coils (8), the angular accelerations applied to the enclosure resulting in differential variations in the inductances of the two coils (8)
