Abstract

MéTODO PARA DETECTAR UM VAZAMENTO DE LìQUIDO, MEIO DE GRAVAçãO LEGìVEL POR COMPUTADOR, E, SISTEMA PARA DETECTAR UM VAZAMENTO DE LìQUIDO Um método e sistema para detectar vazamento de líquido. O sistema inclui um sensor tendo duas linhas condutoras separadas para detectar vazamento de líquido, as duas linhas condutoras separadas tendo dois terminais abertos e dois terminais de conexão; um único gerador para prover um sinal de detecção para detectar líquido com impedância menos que 100 mega ohm ao sensor; e um controlador conectado eletricamente ao terminal negativo (ou terminal positivo) dos dois terminais de conexão. Se vazamento de líquido for detectado entre as duas linhas condutoras, um sinal analógico é gerado no terminal negativo (ou terminal positivo). O controlador converte o sinal analógico em um sinal digital para ativar um alarme.
