@conference{10902/2359, year = {2007}, month = {7}, url = {http://hdl.handle.net/10902/2359}, abstract = {A level and flexible quasi-distributed liquid sensor based on the changes in the light transmittance in a plastic optical fiber cable is proposed. The measurement points are constituted by small areas created by side-polishing on a curved fiber and the removal of a portion of the core. These points are distributed and adapted on each full-turn of a spire of fiber built on a cylindrical tube vertically positioned in a tank. The changes between the refractive indexes of air and liquid generate a signal power proportional to the position and level of the liquid. The sensor system was successfully demonstrated in the laboratory and experimental results of three prototypes with 10, 8, and 5 measurement points and with bend radius of 5mm are presented in this paper.}, publisher = {SPIE Society of Photo-Optical Instrumentation Engineers}, publisher = {Proceedings of SPIE, 2007, vol. 6619, 661917}, publisher = {Third European Workshop on Optical Fibre Sensors, Nápoles, 2007}, title = {Quasi-distributed liquid level measurement with adaptable optical fiber transducers}, author = {Lomer Barboza, Mauro Matías and Quintela Incera, Antonio and Quintela Incera, María Ángeles and Cobo García, Adolfo and López Higuera, José Miguel}, }
