An electrical device for detecting moisture has a detection cable () made up of a first element () and of a second element () which elements are elongate and electrically conducting and separated by a polymer-based material (), and an electrical resistance measurement appliance intended to measure the electrical resistance between the first and second elements of the the cable, where the material () is a non-soluble and moisture-sensitive material.

Electrical device for detecting moisture

The present invention relates to the field of electrical cables to be installed in materials such as concrete or other cement based materials and more particularly but not limitatively to heating cables such as floor heating cables. More precisely, the invention provides an electrical cable comprising an outer protective sheath and at least a conductor within said outer protective sheath, said electrical cable being lead-free and characterized in that it comprises at least an element made of a polymer compound with a sufficiently high density in order to provide an overall specific density of said cable of at least 4.5 g/cm.
