Abstract
This work describes the operation of an optical fiber sensor employed in the determination of remaining oil concentration in oil-biodiesel blends. The sensor is based both on the sensitivity of a long period grating to changes in the surroundings refractive index and on the thermo-optical properties of oil-biodiesel blends. The sensor response is provided by a temperature coded interrogation unit that employs an auxiliary fiber Bragg grating. The standard metrological analysis of an optimized sensor showed that is possible to detect until 0.10%Â v/v of oil in oil-biodiesel blends.
