Paper Abstract

A fiber-optic hydrocarbon vapor sensor system was developed for environmental and industrial process monitoring in spill (alarm, level) and continuous (control) modes. The transducer consists of three optical fibers made reflective and optically coupled at their distal end, and mounted in a capillary. Light from an LED is launched in the source fiber, coupled to sensing and reference fibers at their distal ends, and fed back and monitored at the source. The optical transmission of a sensing fiber section is made sensitive to chemicals to be monitored and exposed to the ambient. Sensor system design and test results are presented. Its transductance can be altered easily by varying the geometry.
