Abstract

Electrostatic triaxial accelerometer comprising a test weight movable with respect to an accelerometer body, electrically connected to said body by a highly flexible lead, electrodes fixed to said body and forming capacitors with respect to the test weight, means for detecting the test weight position by means of measurement voltages fed to said electrodes and means for positioning said test weight by electrostatic forces developed from cueing voltages applied to said electrodes, characterized in that the test weight comprises six planar plates regularly assembled such that the inside volume defined by these plates is a cube with a side smaller in length than the plates.
