Important results from the project
In this project, we developed a fibre optic pressure sensor based on Fibre Bragg Grating, the same underlying technology as commonly used for fibre-optic strain and temperature sensors. The fact that the pressure sensors can be installed on the same optical fibres in series with strain and temperature sensors and be analyzed by the same read-out was an important feature of PRINTS. The primary target application is condition monitoring of pumps and similar machinery, but the project also evaluated the applicability for borehole monitoring with these sensors.
Expected long term effects
The main outcomes of are: 1. A new fibre-optic based pressure sensor protype, validated for integration in relevant machinery 2. A feasibility study and test on PRINTS sensor prototypes for borehole measurements 3. A better understanding of industrial needs for a potential commercial fibre-optic pressure sensor solution
Approach and implementation
In PRINTS, the following tasks were performed: 1.Refining parameters with project partners for optimum application specific performance of pressure device 2.Development of the sensor in parallel with evaluation of its design, packaging, and manufacturability in relation to the specification. 3.Complete lab evaluation of the new prototype 4.Field tests: pressure sensor device integrated in a SCADA system and pressure monitoring in boreholes at SKB
