Abstract
A fluid leak detection system mounts to a hose line segment of the type comprising at least an inner carcass and an outer containment carcass separated from the inner carcass by a collection space. The system includes a housing defined by sidewalls externally mountable to the hose line segment and having an internal housing chamber in fluid communication with the collection space. A system sensor casing mounts through a housing sidewall, the sensor casing having an axial bore and an external sensor casing portion positioned outside of the sensor housing and an internal sensor casing portion positioned inside of the sensor housing. The sensor casing includes a valve assembly that opens and closes responsive to respective coupling and decoupling of a sensor assembly with the external sensor casing portion. A first valve assembly sealing unit opens at or above a preset threshold pressure and closes at a pressure below the preset threshold pressure. A second valve assembly is positioned at an inward location within the axial bore, and opens responsive to coupling engagement between the sensor assembly and the external sensor casing portion and closes responsive to disengagement of the …
