Abstract

Patente de Invenção: "CIRCUITO DE MEDIçãO E PROCESSOPARA A DETERMINAçãO DE CONCENTRAçõES DEFULIGEM". A presente invenção refere-se a um circuito demedição com um sensor de fuligem numa tubulação de gás paragases, contendo partículas de fuligem e sua utilização, tambémrefere-se a um processo para a determinação de umaconcentração de fuligem em correntes de gás contendo partículasde fuligem, sendo que pelo menos uma corrente parcial de umacorrente de gás contendo partículas de fuligem passa por e/ouatravessa numa tubulação de gás pelo menos um objeto queconduz eletricidade. A tarefa é, disponibilizar um sensor e umprocesso para a determinação de concentrações de fuligem emcorrentes de gás, com os quais podem ser avaliadas tambémquantidades pequenas de fuligem. A tarefa é solucionada por meiode um circuito de medição com um sensor de fuligem possuindo umobjeto condutor de eletricidade com uma carga elétrica, onde éprevisto no gás, a montante do sensor de fuligem, um dispositivopara a geração de uma outra carga elétrica nas partículas defuligem. A tarefa também é solucionada, sendo que o sensor defuligem possui um objeto conduzindo eletricidade que é colocadoem potencial de massa e que no gás é previsto, a montante osensor de fuligem, um dispositivo para a geração de uma cargaelétrica nas partículas de fuligem.
