Patent ID: 7081759

Claim:
A substantially flat four-conductor water detection cable comprising: a first sensing lead that has a center conductor that is at least partially surrounded by a conductive polymer ends non-conductive polymer that is porous to water and that at least partially surrounds said conductive polymer, said non-conductive polymer providing an insulating layer at least partially surrounding said conductive polymer; a first monitor lead that has a center conductor that is surrounded by a non-conductive polymer, said first monitor lead disposed adjacent and joined to said first sensing lead along a substantially flat plane; a second monitor lead that has a center conductor that is surrounded by a non-conductive polymer, said second monitor lead disposed adjacent and joined to said first monitor lead along said substantially flat plane; and a second sensing lead that has a center conductor that is at least partially surrounded by a conductive polymer and a non-conductive polymer that is porous to water and that at least partially surrounds said conductive polymer, said non-conductive polymer providing an insulating layer at least partially surrounding said conductive polymer, said second sensing lead disposed adjacent and joined to said second monitor lead along said substantially flat plane to form a substantially flat four-conductor water detection cable.
