Abstract
This work presents a sensing system based on an etched fiber Bragg grating, applied to the refractometric analysis of water-ethanol mixtures. The system configuration employs one etched-FBG operating at two temperatures, (20.0 ± 0.5) °C and (3.0 ± 0.5) °C. The sensing system performance in measuring the ethanol-water proportions is evaluated in the concentration range between 0.0 and 100.0 % v/v of water in ethanol, resulting in uncertainties less than 3.9 % v/v. The sensor capability to determine the ethanol concentration is shown, even for the range of concentrations where the correlation between refractive index and ethanol proportion in the sample presents an ambiguous behavior.
