ABSTRACT:
A detection and location system, e.g. for liquid leaks, comprising a trunk line sensor cable and a plurality of branch line cables at intermediate points of the trunk cable. Each of the cables comprises two insulated conductors and two non-insulated conductors, e.g. conductive polymer-coated wires, which become connected upon occurrence of a leak. In one embodiment, each of the insulated conductors in the trunk line is continuous and each of the non-insulated conductors is discontinuous at each intermediate point; the branch line conductors are respectively connected to the discontinuous ends of the non-insulated trunk line conductors, and are connected in pairs of one insulated and one non-insulated conductor at the end of each branch. In another embodiment, in the trunk line, both the non-insulated conductors and one of the insulated conductors are continuous and one of the insulated conductors is discontinuous at each intermediate point; in the branch line, the two insulated conductors are respectively connected to the discontinuous ends of the insulated trunk line conductor at the intermediate point, and to each other at the end of the branch, and the two non-insulated conductors are respectively connected to the non-insulated trunk line conductors but are not otherwise connected.
