Abstract

SENSOR óPTICO DE TEMPERATURA E PRESSãO E USO DO MESMO é descrito um sensor óptico (100) de pressão e temperatura para ser fixado em uma estrutura portadora, onde dito sensor compreende conectores ópticos (51, 51<39>) fixados em alojamentos (21, 21<39>) usinados em pinos (11d, 11d<39>) integrais aos ditos corpos cilíndricos (11c, 11c') e dotados de roscas (20, 20<39>); corpo (11a) propriamente dito do sensor, de formato geralmente retangular, com arestas (12) arredondadas e superfícies (13), (18) e (22), dito corpo (11a) sendo solidário ao corpo cilíndrico (11c), e de geometria tal que a diagonal maior é igual ou menor que o diâmetro do como cilíndrico(11c) de forma a apresentar sempre uma distância (11b) entre a superfície do corpo (11a) e a tangente axial paralela à dita superfície no corpo cilíndrico (11c) de forma que o corpo (11a) esteja sempre em balanço em relação ao corpo (11c), e onde dito corpo (11a) tem: b1) um primeiro rebaixo (13a) na superfície (13) para formação de uma das superfícies da membrana (17), no dito rebaixo (13a) sendo alojados: um bujão (31) dotado de canal (32) e um anel elástico (41) de trava; e b2) um segundo rebaixo (18a) na superfície (18) oposta à dita superfície (13), dito rebaixo definindo a espessura da dita membrana (17); e uma fibra óptica (15) contendo pelo menos duas redes de Bragg (16a, 16b) fixadas sobre a dita membrana (17), a dita fibra (15) sendo integralmente contida no interior do dito sensor entre os conectores ópticos (51, 51<39>) através de canais (15a, 15a<39>) e um dispositivo de conexão flexível (23), pelo que é garantida a ausência de efeito de offset de pressão e temperatura na medição efetuada. Um sensor óptico (200) alternativo é igualmente descrito, bem como os usos dos mesmos.
