ABSTRACT:
The means for the capacitive measurement of displacements includes a scale in the form of a belt (10) movable longitudinally in relation to a measuring device which is provided with several groups of electrodes (22 to 25) connected by lines (27) to an electronic means. The belt (10) is made of metal and is provided with a plurality of regularly spaced rectangular openings (11). The belt (10) constitutes, with the transmitting electrodes (22 to 25) and a receiving electrode (29) situated relative to the transmitting electrodes, a differential condenser permitting the accomplishment of capacitive measurement of displacements.
