ABSTRACT:
A leak sensor and a leak sensing system are provided. The leak sensor preferably includes a fluid sensing member that is capable of sensing and indicating the presence of a fluid leaked from a fluid storage or transport member. The leak sensor further preferably includes at least two wires communicating with the fluid sensing member. The wires are preferably configured to be short-circuited when they contact the fluid leaked from the fluid storage or transport member. An electrical signal corresponding to a leak sensor location can thereby be sent to a control terminal of the leak sensing system. A portion of the wires may be arranged in a cable coated with a protective material such as Teflon®. The control box (or terminal) preferably receives electrical signals from a plurality of leak sensors. The electrical signals can provide information on whether the fluid has leaked and on which leak sensor or sensors have detected the fluid leak.
