Abstract

In a data transmission system for a pipeline which is electrically conductive at least in sections, the pipeline itself forms a data line. For this purpose, a coupling element is present for the modulation of electrical signals onto a potential of the pipeline. A cost-effective data transmission system is created which can be used in remote regions.
