Corrosion detection apparatus for monitoring a state of corrosion

摘要

A corrosion detection apparatus for permanently and integrally monitoring a state of corrosion of a component is provided. The corrosion detection apparatus makes it possible to use the change in electrical conductivity to detect corrosion of a component to be monitored. A corrosion-sensitive bridging element that establishes an electrical connection between a first electrical line section and a second electrical line section of a sensor circuit is used to change certain electrical properties of the sensor circuit. On account of the corrosion-sensitive property of the bridging element, the latter changes its electrical conductivity when corrosion starts. This makes it possible to use the sensor circuit to detect corrosion of the bridging element and thus of the component to be monitored.
