Abstract:
A capacitance-coupled contactless displacement/angular position sensor comprising:a carrier (10);a potentiometer path (20), arranged on the carrier (10), an alternating voltage is appliable to the potentiometer path;a collector path (30) arranged on the carrier (10);a first probe (70) guided for displacement above the potentiometer path (20);a second probe (80) electrically coupled with the first probe and guided for displacement above the collector path; andscreening surfaces (11, 12, 13, 14) connected to frame potential surround the potentiometer path (20) and the collector path (30) and the probes guided above them so that both the potentiometer path (20) with the first probe associated to it and the collector path (30) with the second probe associated to it are each arranged in a spatially separate screened space (22,32).
