Abstract
A leak detector (190) includes a sensor head (260), a light source (200) optically coupled to the sensor head and operable to generate excitation light. A detector (205) is optically coupled to the sensor head and operable to detect fluorescence light. A signal processing unit (210) is coupled to the detector and operable to signal a leak condition responsive to an intensity of the fluorescence light exceeding a threshold. A fluid-tight enclosure (235) encloses at least the light source, the detector, and the signal processing unit.
