Abstract

Optical fibre and sensor based systems have been developed for monitoring in industrial environments where conventional instrumentation is either prohibited or inoperative because of a variety of hazards or difficulties. The systems are based upon sophisticated forms of wavelength encoding but nonetheless utilise robust and inexpensive instrumentation. They have a major attraction of utilising unified instrumentation for monitoring a variety of parameters. Preliminary results from two industrial on-site demonstration projects are presented. These involve monitoring pressure, temperature, mass density, radiation and rotary speed at a chemical plant with an explosion hazard and an electric power testing plant with extra high voltage and severe electromagnetic interference hazards. Both applications require long term monitoring reliability for pressure and temperature which the demonstration projects have shown to be within the capability of the newly developed system technology. The application of such optically based monitoring systems already promises to lead to significant improvements in production efficiency at the chemical plant and to reduce outage times and saving in servicing costs of in service circuit breakers.
