Abstract

An acceleromter having a test weight movable in relation to a frame includes three pairs of mutually electrically orthogonal conducting parallel faces (1-6). Electrodes connected to the frame form capacitors with faces of the test weight. The six faces form two sets of three faces (1-3) and (4-6). The faces of a set form a first conductor insulated from the faces of the second set which form a second conductor. Position sensing voltages are applied to first and second conductors through very flexible leads (7 and 8). Position control voltages derived from the position sensing voltages are applied to the electrodes.
