Abstract

A cable suitable for detecting the presence of corrosive liquids is disclosed. In an embodiment the cable includes two sensing wires wrapped around a core member, at least one of the sensing wires being surrounded by a non-conductive surface layer. In an alternate embodiment the cable includes two sensing wires wrapped around a core member, the sensing wires and core member being encapsulated by a non-conductive surface layer. Preferably, the cable includes insulating wires for detecting the location of a leak. When a corrosive liquid contacts the sensing wires of the cable an electrical connection is created between them.
