摘要：A device comprising a capacitive transducer comprised of a fixed membercomprising first and second axially separated equal diameter metallic electrode rings anda movable member comprised of a thin walled metallic cylinder separated from the fixedmember by an annular gap such that said movable member capacitively couples said firstand second rings of the fixed member. The first ring of the fixed member is comprised ofa continuous metallic ring glued onto an insulating supporting means, and the secondring is comprised of four thin metal foil electrodes separated by four equi-width narrowgaps spaced at angular intervals of 90° and glued onto an insulating supporting means.The first electrode ring of the fixed member is electrically connected to an alternatingcurrent power source and each pair of diametrically opposed electrodes of the secondring of the fixed member are electrically connected to a position control loop circuit.
