Abstract

<B>" PROCESSO DE MEDIçãO DE HIDROGêNIO PERMEADO EM ESTRUTURA METALúRGICA E APARELHO CORRESPONDENTE "<D>, refere-se a processo de medição de fluxo de hidrogênio permeado em máquinas, equipamentos, tubulações ou outros aparelhos metálicos utilizados na indústria de petróleo, refinarias, indústrias químicas, indústrias petroquímicas, unidades de produção, bombeamento, transporte e estocagem de petróleo e gás, tanques, máquinas e equipamentos que trabalham com hidrogênio ou compostos que gerem hidrogênio e indústria nuclear, através de sensor que utiliza propriedades de junções de materiais dissimilares em adequada construção e instalação para medição de grandezas elétricas entre uma junção de medição ( 2-a ) e uma junção de referência ( 2-B ), com baixo custo de construção e com tempo de vida ilimitado por não usar materiais de consumo, com alta velocidade de resposta, com acurácia e precisão equivalentes ou melhores que os processos de medição convencionais, com instalação extremamente simples e barata, com baixo custo de manutenção e com fácil integração a computadores de processo digitais ou analógicos.
