Abstract
The shipboard environment, with its potential for extreme EMI levels, electrical problems, flooding, fire and other damaging conditions, is particularly well suited to benefit from fiber optic based sensing technology. Eldec Corporation has been involved in the development of such sensors and this paper outlines some of the issues related to that development, including an examination of the particular requirements of shipboard systems and how those requirements affect development of general purpose fiber optic based sensors. The tradeoffs between passive fiber optic transducers and equivalent self-powered electric 'active' devices using fiber optic signal lines are examined. Additionally, a basis for the development of these 'active' sensors will be presented, along with descriptions of a non-contacting limit switch and linear position sensor equivalent in function to the LVDT linear variable differential transformer.
