Leak detector with sensing cable

A leak detector comprising:

• a housing;
• a processor located within the housing;
• a wireless communications module operable to communicate with a remote device;
• an impendence sensor operable to measure changes in impedance along a sensing circuit;
• and
• a leak sensing cable, electrically in communication with the impedance sensor, the leak sensing cable comprising:
• an inner core, having a first conductive thread electrically connected to the sensing circuit;
• an inner sheath, coaxially located around the inner core, the inner core being comprised of a permeable, non-conductive material;
• an outer sheath, coaxially located around the inner sheath, the outer sheath comprising a permeable braided material and having a second conductive thread woven into the permeable braided material, the second conductive thread being electrically connected to the sensing circuit;
• and
• wherein the first conductive thread is substantially electrically isolated from the second conductive thread when the leak sensing cable is dry and less electrically isolated from the second conductive thread when the leak sensing cable becomes wet.
