    • A fluid leak detector is provided for a double carcass hose line segment and includes a sensor housing defined by sidewalls externally mounted to the hose line segment and having an internal housing chamber in communication with the collection space. An optical sensor is mounted through at least one sensor housing sidewall and positions an optical sensing element means within the sensor housing chamber for detecting a presence of fluid in the hose collection space. The optical sensor further includes analysis element means connecting to the optical sensing element means and positioned outside of the sensor housing one, wall, the analysis means generating data indicative of the fluid status within the hose collection space; and transmitter element means connecting to the analysis means for receiving data from the analysis element means and transmitting the data to at least one remote receiver. T optical sensing element means is electrically isolated from the analysis means and comprises at least one optical fiber positioned to make contact with fluid leaking into a collection space between the two carcasses of the hose.

    • 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 sensor assembly from the external sensor casing portion. A biasing spring biases the first and second sealing units into respective closed positions.
    • 流体泄漏检测系统安装到包括至少内胎体和外容纳胎体的软管线段,所述胎体和外容器胎体通过收集空间与内胎体分离。 该系统包括由外部可安装到软管线段的侧壁限定的壳体,并具有与收集空间流体连通的内部容纳室。 系统传感器壳体通过壳体侧壁安装,传感器壳体具有轴向孔和位于传感器壳体外部的外部传感器壳体部分和位于传感器壳体内部的内部传感器外壳部分。 传感器外壳包括响应于传感器组件与外部传感器外壳部分的相应耦合和解耦而打开和关闭的阀组件。 第一阀组件密封单元在预设阈值压力以上开启并在低于预设阈值压力的压力下关闭。 第二阀组件位于轴向孔内的向内位置,响应于传感器组件和外部传感器外壳部分之间的联接接合而打开,并响应于传感器组件与外部传感器外壳部分的脱离而闭合。 偏置弹簧将第一和第二密封单元偏压到相应的关闭位置。
