capacitive verschiebungsmessfuehler and torsionswinkelaufnehmer using such a capacitive fuehlers.

摘要

The invention relates to the capacitive sensors designed to measure the displacements, whose amplitudes are very low, of two zones a, b, with respect to one another. / p & & p & it comprises a capacitive element made of two supports 1, 2 fitted into one another and with the facing cylindrical surfaces, which bear electrodes c0, c1, c2. These two supports 1, 2 are respectively rigidly connected to the two zones a, b, so that the capacitance of the capacitors formed by the electrodes of the facing surfaces of which varies as a function of the relative movements of the two zones; thus, the measurement of the displacement is effected by a measurement of the capacity variation. / p & & p & the application, in particular, to the embodiment of the sensors of the angle of torsion.
