Abstract

"APARELHO E MéTODO PARA MEDIR A PERMEABILIDADE OU CAPACIDADE DE FILTRAGEM EM MATERIAIS PERMEáVEIS". O aparelho 10 para medir a permeabilidade de um material 12 inclui uma fonte 14 de vácuo consideravelmente constante acoplada por meio do duto 11 a um recipiente de capacitância de fluido 16 que contém um transdutor de pressão 18 acoplado por condutores 20 a um amplificador e mostrador 22 para monitoração da fonte 14. O disco 24 impermeável ao fluido é provido com colocação na superfície 26 do material 12. Para definir, entre o disco 24 e a superfície 26 uma cavidade 28 de fluxo de fluido. O disco 24 é acoplado por conduto 32 a um tubo de restrição 30 que oferece alta impedância ao fluxo do fluido. Uma extremidade oposta do tubo de restrição 30 está em comunicação de fluidos com o recipiente 16. Um transdutor 34 está acoplado através do tubo de restrição 30 para oferecer uma medida do fluxo do fluido. a vedação da impermeabilidade do fluxo 60 forma uma vedação em torno da periferia do disco 24 e se estende externamente no raio da área 26. Presumindo-se que o material 12 tenha certo grau de permeabilidade, o ar será capaz de permear o material 12 para além da periferia da vedação 60 e até a cavidade 28. Tal fluxo produz um estado estável de diferencial de pressão através do tubo 30 detectado pelo transdutor 34 que pode ser lido a partir do mostrador 38, para oferecer uma medida de permeabilidade.
