Abstract
" SENSOR DE pH A FIBRA óPTICA". é descrito um sensor de pH (100, 200, 300) a fibra óptica onde um transdutor acopla mecanicamente uma rede de Bragg a um hidrogel sensível a pH, o sensor compreendendo uma parte central (110, 210, 301) onde são colocados a fibra óptica (121) contendo a rede de Bragg (122), o conjunto (130) de discos de hidrogel sensível a pH, e o transdutor mecânico que é uma mola (123) uma viga (215) ou ainda a própria fibra óptica (121), o transdutor mecânico garantindo a deformação sobre a rede de Bragg (122). A variação do volume hidrodinâmico do hidrogel resultante de uma variação do pH do meio introduz uma força suficiente para deformar a rede de Bragg. A medida da variação do pH é recuperada empregando as técnicas usuais de leitura de comprimentos de onda. O sensor de pH (100, 200, 300) da invenção é útil na avaliação indireta, no controle e na monitoração da corrosão em poços de petróleo e é adequado para multiplexação com outros sensores a fibra óptica que medem o mesmo parâmetro ou parâmetros diferentes.
