ABSTRACT:
A method for the signal processing of capacitive measurement scales intended for the measurement of lengths or angles, consisting of two parts moveable relative to each other provided with electrodes that together form condensers, whose magnitudes are variable and depend on the relative position as specified by a sinusoidal relationship between the two parts. The first part has n electrodes evenly distributed over one measurement period and the second part has one electrode per measurement period. The electrodes in the first part are fed with n alternating voltages whereby the time displacements of the alternating voltages relative to each other aret0n,, where t0is the length of the period of the alternating voltage. The electrode of the second mobile part captures a signal composed of one or several of the alternating voltages and the amplitude composition of the signal depends on the relative position between the two parts.
