ABSTRACT:
A sensor for detecting leakage of a particular fluid into an area to be monitored, such as an interstitial space of a double-walled tank or pipeline, comprises first and second fiber optics. A first end of the first fiber optic is disposed to a source of light and a first end of the second fiber optic is disposed to a detector of light. The second ends of the fiber optics are axially aligned with one another. Under normal circumstances light is transmitted from the source to the first fiber optic across the gap into the second fiber optic, and is detected by the detector. The fiber optics are arranged such that when the sensor is exposed to a material to be monitored, effective light-transmission between the second ends of the fiber optics is prevented, preventing light from being transmitted from the source to the detector. This provides a simple and fool-proof method of detecting leakage of the fluid to be monitored into the area to be monitored.
