摘要: A capacitive displacement meter or transducer of co-axial set-up is disclosed. At least one cylindrical inner electrode element placed coaxially within at hollow outer element. The and elements are movable relatively to each other. One comprises three axially spaced aligned, electrodes, which the end electrodes equally long intermediate middle shorter than electrodes. other extending said and, in an inoperative position, being symmetrically juxtaposed electrode. two provided with terminals.
