The issue of selecting appropriate sensors enabling correct strain transfer is discussed in the article, indicating both limitations of layered cables and the advantages of sensors with monolithic cross-section design in terms of reliable measurements. The results obtained thanks to monolithic DFOS sensors are presented on the example of real engineering structure – the Burakowski concrete collector in Warsaw during its strengthening with glass-fibre reinforced plastic (GRP) panels.
