Abstract
A device for indication of water leakages in a heat insulated pipeline (1) which consists of carrier supporting a pair of spaced electric conductors (5). The electric conductors (5) are arranged in a strip-shaped cover comprising two surface layers (4, 6) of an electrically insulating material. At least one surface layer (6) is liquid absorbing and/or soluble by the liquid. The surface layers (4, 6) are interconnected by an adhesive layer (8) and one outer surface of one cover is provided with a second adhesive layer (9) intended to be attached to the pipeline (1) and which in the inactive, unapplied position of the detection means is covered by a protective film.
