Abstract

"TRANSDUTOR DE PRESSãO DIFERENCIAL A FIBRA óPTICA". é descrito um transdutor (100, 200, 300, 400) de pressão diferencial a fibra óptica contendo redes de Bragg (118), dito transdutor sendo usado para medir a pressão diferencial em um Venturi instalado no interior de um duto (1) por onde se desloca um fluido como petróleo. O transdutor compreende um corpo (110, 230, 360, 410) de diferentes geometrias e um diafragma (2), pelo menos uma rede de Bragg (118) sendo afixada sobre cada uma das superfícies do mesmo. O diafragma (2) é colocado paralelo ou transversal ao corpo do transdutor (100, 200, 300, 400). O transdutor (200) é isolado do fluido de processo por selos mecânicos (201) flexíveis que transmitem a pressão até as superfícies do diafragma (2). O transdutor (300, 400) é dotado de duas microválvulas de alívio para efeitos de proteção do sensor ¢diafragmas (2)! em casos de sobre pressão.
