Abstract

CIRCUITO DE MONITORAçãO DA CONDUTIVIDADE DA áGUA PARA USO COM UM GERADOR A VAPOR. A presente invenção refere-se a um circuito de monitoração de condutividade de água determina o estado de um filtro trocador de íon no fluxo de água para um gerador de vapor. Um microprocessador envia um sinal de referência para um circuito sensor de condutividade que o converte em um sinal de estimulo que é enviado para uma sonda no fluxo de água. Qualquer condutividade da água altera o sinal de estimulo, e o sinal modificado é comparado ao sinal de referência para estabelecer um valor indicativo da condutividade da água. O microprocessador compara o valor a pelo menos dois limites representativos do estado do filtro.
