发明名称 Capacitive distance sensor
摘要 A capacitive distance sensor is provided having an elongated sensor element. The sensor element comprises a cylindrical carrier body, which is made of an electrically non-conductive material and has a round cross-sectional areas, and a sensor area which substantially surrounds the carrier body in the manner of a sheath and is made of an electrically conductive material.

主权项 1. A capacitive distance sensor comprising: an elongated sensor element that comprises: a cylindrical carrier body of an electrically non-conductive material having a circular cross sectional area made of a solid uniform material; and a single sensor layer circumferentially surrounding the carrier body in the manner of a sheath of an electrically conductive material, wherein the single sensor layer is supplied with an alternating current such that an electrical field forms outside of the sensor layer, wherein an electrical capacitance changes if an object enters the electrical field, and wherein a change in electrical capacitance is detected by the capacitive distance sensor.
