Abstract

Patente de Invenção: <B>"INSTALAçãO DE VIGIL‰NCIA DE UM APARELHO DE GERAçãO DE ATMOSFERA"<D>. A presente invenção refere-se a uma instalação (16) de vigilância de um aparelho (10) de geração de atmosfera, do tipo que possui meios (32, 34) de medição de pelo menos um parâmetro representativo do funcionamento real do aparelho, ligados a meios de exploração dos valores do ou de cada parâmetro representativo. Os ditos meios de exploração possuem: - meios (44) de memorização dos valores tomados no decorrer do tempo pelo ou por cada parâmetro representativo, - meios (46) de avaliação da deriva do ou de cada parâmetro representativo no decorrer do tempo, e - meios (48) de acionamento de uma intervenção no dito aparelho (10) em função da dita deriva, antes que os ditos valores do ou de cada parâmetro representativo atinjam valores críticos predeterminados.
