Abstract: A sensor cable of conductive and non-conductive liquids leaks for example stored in a tank or flowing in a pipe. The cable is composed of a main body and at least one sensor element made of a central wire surrounded by an insulating sheath, itself integrated in an expandable conductive sheath, the wire and the expandable conductive sheath being arranged to contact conductive and non-conductive fluids, the main body being formed by extruding a plastic material and extruded on a central support in the form of either a plastic rod or a metal rod coated with plastic. This can be applied to liquid leakage watch systems.
