Fiber optic sensor system for high temperatures

Purpose and goal:

In this study, a fiber optic sensor system for continuous monitoring of high temperatures is developed. The goal is to develop an optical fiber with stability at these temperatures, an efficient manufacturing of the fiber optic sensor, and a sensor system that enables temperature monitoring up to 750°C for higher safety and more energy and resource efficient industrial processes.

Expected results and effects:

It is often difficult to use conventional technologies in applications that require many measurement points, and fiber optics can enable significantly simplified installations and reduced weight/size of the sensors. The market for fiber optic sensors is predicted to increase significantly in the coming decade, especially in demanding environments. This project, if successful, will contribute to Swedish competitive solutions in the area.

Approach and implementation: The results from a Vinnova-funded feasibilty study is further developed, in cooperation between the project parties.
