Abstract

"SISTEMA DE CONTROLE DE COMBUSTìVEL PARACONTROLAR O QUEIMADOR DE UM APARELHO ACIONADO AGáS EMPREGANDO UMA CHAMA PILOTO CONSTANTE EPROCESSO PARA ADAPTAR UM SENSOR DE VAPORESINFLAMáVEIS A UM CIRCUITO DE CONTROLE DE VáLVULA".Um dispositivo de segurança para interromper o fluxo de gás paraaparelhos alimentados a gás, na presença de vapores inflamáveis.Um sensor de vapores inflamáveis e introduzido no circuito,suprindo energia proveniente do termopar a uma válvula acionadaa solenóide. O sensor responde à presença de um vapor inflamávelaumentando - sua resistência. Quando é atingida umaconcentração crítica de vapores inflamáveis, há uma queda detensão no sensor, que faz com que a válvula acionada a solenóidese feche.
