Abstract

Patente de Invenção: <B>"DISPOSITIVO DE MEDIDA DO TEOR DE UM MEIO GASOSO EM OXIGêNIO"<D>. O dispositivo compreende um captador capaz de fornecer uma tensão representativa da relação entre uma pressão de oxigênio de referência e a pressão de oxigênio em um volume do captador e munido de eletrodos (12, 14), permitindo fazer passar uma corrente de bombeamento que controla essa pressão de oxigênio no volume e meios de controle/comando que têm um controlador numérico (26) que recebe essa tensão representativa sobre uma entrada e capazes de fornecer a corrente de bombeamento. Esses meios de controle/comando fornecem a corrente de bombeamento sob a forma de uma corrente de variação contínua e progressiva, não cortada, comandada pelo controlador numérico, de modo a submeter a tensão de entrada a um valor determinado.
