ALL-FIBER VIBRATION SENSORS FOR STEEL INDUSTRY

Abstract

<p>This thesis explores the design, fabrication, and experimental application of a variety of all-fiber vibration sensors, based upon a Michelson interferometer design. These sensors can be used to detect vibration in the low frequency regime. It also provides motivation for its use as an inexpensive yet rugged sensor for use in the harsh environment of a steel hot mill as part of an overall preventative/predictive maintenance program since commercially available piezoelectric sensors currently in use have significant reliability problems.</p> <p>While this work did result in a device that could withstand the steel hot mill surroundings and detect low frequency vibrations, higher sensitivities are expected from further optimized devices.</p>
