Abstract

"CONTROLE DE OPERAçõES DE DOSAGEM QUìMICA, BASEADO EM UMA DECALAGEM DE CONDUTIVIDADE". Descreve-se um sistema e processo para controle de operações de dosagem química, baseado em uma decalagem de condutividade determinada para uma solução química. As operações de dosagem química são realizadas pela, ou em conjunto com a, operação de um dispositivo utilitário, tal como uma máquina lavadora de artigos. A solução química é formada em um dispositivo de tanque, pela combinação de água com pelo menos um componente de produto químico. A decalagem de condutividade, que é a condutividade da água, é usada para normalizar a condutividade estimada para a solução química relativa ao componente de produto químico na solução. Durante vários instantes de tempo durante a operação do dispositivo utilitário, a condutividade normalizada é comparada com um ponto de referência da condutividade e, se a condutividade normalizada cair abaixo do ponto de referência da condutividade, um volume especificado do componente de produto quimico é alimentado ao tanque de solução.
