An electrode array for use in an apparatus for remotely monitoring the position of a rotatable member as the rotatable member is rotated by an axle about an axis. The array includes a substrate composed of a three-layer composite having first and second surfaces, a plurality of spaced-apart, excitable electrodes defining a center portion disposed on the first surface, an aperture in the substrate located in the center portion for receiving the axle, a center electrode in the center portion spaced apart from the axle circumscribing the aperture, a guard composed of a first conductive strip disposed in the center portion on the first surface spaced apart from and located between the spaced apart excitable electrodes and the center electrode. Each of the excitable electrodes have a concave free edge that delimits a part of the center portion. The excitable electrodes and the meter hand have predetermined areas, so that the area of any given member of the excitable electrodes subtended by the meter is substantially constant as the meter hand traverses across such electrode.
