LEAKAGE DETECTION FOR PRESSURIZED FUEL TANKS

The present invention relates to leakage detection for pressurized fuel tanks. In order to provide facilitated leakage detection, a leakage detection device (10) for pressurized fuel tanks for storing a pressurized fuel is provided that comprises a fuel-sensing tracer (12) and a light-wave conducting component (14). The fuel sensing tracer is configured to alter its optical properties in the presence of a predetermined fuel. The light-wave conducting component is in optical contact with the fuel sensing tracer. Light travelling within the light-wave conducting component is modifiable by altered optical properties of the fuel sensing tracer such that modified light is indicative of the presence of fuel at the location of the fuel sensing tracer. This allows a detection of a leakage with minimized means due to the optical detection approach.
