Sensor system for monitoring surroundings on a mechanical component, and method for actuating and evaluating the sensor system

摘要

A sensor system for monitoring surroundings on a mechanical component, includes at least one capacitive sensor element that is attachable to the surface of machines or machine parts, the at least one sensor element being constructed from a layered structure of flexible electrically conductive and electrically insulating plies, electrically conductive potential surfaces of one ply being disposed, laterally spaced apart via insulating plies located therebetween, in such a way that electric field lines form between the conductive potential surfaces and change measurably upon proximity and/or contact of a body or an object. The layered structure of a sensor element has at least two measuring elements operating separately from one another.

1. A sensor system for monitoring surroundings on a mechanical component, comprising:
at least one capacitive sensor element attachable to a surface of the mechanical component and having a layered structure of electrically conductive and electrically insulating plies; wherein electrically conductive potential surfaces of a selected ply are disposed, laterally spaced apart via insulating plies located therebetween, so that electric field lines form between the conductive potential surfaces of the selected ply and change measurably upon at least one of (i) proximity of the sensor element with one of a body or an object, and (ii) contact between the sensor element and one of the body or the object; wherein the layered structure of the sensor element has at least two measuring elements configured to operate separately from one another, and wherein the at least two measuring elements are situated on an insulating layer of the at least one capacitive sensor element.
