Characterization of Influence Quantities for the Uncertainty Evaluation of Fiber Bragg Grating and Fabry–Pérot Fiber-Optic Thermometers – supporting dataset

This dataset contains the measurement data underlying the figures of the article "Characterization of Influence Quantities for the Uncertainty Evaluation of Fiber Bragg Grating and Fabry–Pérot Fiber-Optic Thermometers" (MDPI Metrology). The measurements were performed within the European Partnership on Metrology project INFOTherm (22IEM07) at the University of Maribor (UM), Physikalisch-Technische Bundesanstalt (PTB), Danish Technological Institute (DTI) and Czech Metrology Institute (CMI). FBG and FPI sensors fabricated from standardized single-mode fibers were characterized for pressure–temperature, vibration–temperature, strain–temperature and humidity–temperature crosstalk. In addition, FBGs in different packages (fused-silica, alumina, stainless-steel and Inconel tubes) were compared in terms of their wavelength drift during thermal aging at 700 °C to 900 °C. The influence of temperature and relative humidity on three different FBG interrogators was also measured, and the Hyperion Si255 interrogator was calibrated. The data are provided as CSV, TXT, and XLSX files. The README file links each file to the corresponding figure and panel of the article.
