Purpose and goal
The objective was to investigate the added value of a combination of distributed fiber sensor technology and well established Fiber Bragg grating technology in applications such as machine condition monitoring. The aim has been to identify and evaluate methods to get more information from sensor installations, thereby increasing their value. The study has identified a feasible technology combination that maintains the full performance of the FBG´s and adds information on other variables through distributed measurements. The combination is of great interest to the industry.
Expected results and effects
The main outcome of the feasibility study is a proposed and demonstrated a method that combines distributed measurements and FBG measurements in a way that well meets the needs expressed by the relevant industry. The performance improvements provided by the proposed technology significantly increases the sensitivity and the sampling frequency of relevant data from the fiber installation. This results in important advantages in terms of performance and systems simplifications in a possible future product.
Planned approach and implementation
Research and development activities have been carried out by Rise Acreo whose primary task has been assess the attainable performance through theoretical and experimental work, and to point out a direction for further development. SKF, who wants to integrate the developed technology in their products, have contributed with requirements specification and requirements analysis. They also contributed with valuable competence and experience of fiber-optical integration in their components.
