Abstract
Disclosed are aqueous chemical leak detection cables that provide protection to sensor wires by using a conductive polymer coating that is resistant to corrosion by aqueous chemicals. In addition, non-conductive, liquid pervious layers may surround one or more of the sensor wires to assist in preventing false detection of an aqueous chemical leak as a result of various non-liquid contaminants. The non-conductive, liquid pervious layer may comprise spirally wrapped or braided, non-hydroscopic, non-conductive monofilament fibers, or a continuous, non-conductive pervious coating.
