Abstract

The U.S. Navy is developing fiber optic temperature sensors to detect shipboard fires for the damage control monitoring system. For fire detection, continuous measurements of temperature are required to a value of 1100 degree(s)C in every compartment, in addition to other measurements. Fire detection information is transmitted on a fiber optic data network for display to the ship's damage control officer. Fabry-Perot, black body, and microbend sensors were evaluated on a Navy ship, the ex-USS SHADWELL, to determine ability to detect fires. Results demonstrated the ability to measure temperatures up to 1100 degree(s)C with no deleterious effects from the shipboard environment of high humidity, vibration, and shock. Further research and development has revealed additional fiber optic sensor technology, based on other techniques, that is also capable of high temperature measurement onboard ship. Multiplexing is being used to reduce sensor cost.
