Abstract (en)

[origin: DE19718024A1] The invention relates to a path/angle sensor, comprising a potentiometer track (20), arranged on a support (10), said track being subjected to an alternating voltage, a collector track (30) also arranged on said support (10), a first probe which slides over the potentiometer track (20), and second probe which slides over the collector track (30) and which is connected electrically to the first probe. The invention is characterized in that shielding surfaces (11, 12, 13, 14) are provided, said shielding surfaces corresponding to an earth potential. These shielding surfaces surround the potentiometer track (20), the collector track (30) and the probes guided over these tracks in such a way that both the potentiometer track (20) with its designated first probe and the collector track (30) with its designated second probe are arranged in shielded spaces (22, 32), separately from each other.
