Important results from the project

The goal of the project was to develop a lab demonstrator where Insplorion´s NPS hydrogen detection technology was combined with Saab´s existing optical sensor readout unit. This objective was met and the demonstrator´s function was verified in Insplorion´s laboratory.

Expected long term effects

Saab´s readout unit is currently used in the temperature monitoring system on board Airbus A350. By demonstrating that this readout unit can also be used to read Insplorion´s hydrogen sensors, the development time and cost of a finished product are shortened. It also demonstrates the potential of using one and the same readout unit to read multiple types of sensors, which would lead to both cost and weight savings for aircraft manufacturers.

Approach and implementation

Insplorion was responsible for adapting the sensing structure and for the design and manufacture of the "fiber cap", aligning and immobilizing the optical components and the sensing element. Saab and Insplorion were jointly responsible for the selection of optical components. Saab was also responsible for making the necessary changes to the readout unit software. All tests with hydrogen gas were done jointly in Insplorion´s lab. The collaboration has been constructive and effective.
