Abstract

"MéTODO PARA MONITORAR A CONDIçãO DE FLUIDO EM UMA TRANSMISSãO AUTOMáTICA EM TEMPO REAL". Uma sonda tubular tendo eletrodos anularmente espaçados é imersa em ATF e seq³encialmente excitada com uma voltagem alternada em uma freq³ência relativamente baixa e alta. A corrente é medida em ambas freq³ências e a diferença em impedância computada; e, a impedância diferencial é corrigida para temperaturas e o valor correspondente de um de TAN pela ASTM D-669, Oxidação delta pela ASTM E-168 (<30>OX) e tempo de indução de HPDSC pela ASTM D-5483 (MIN) determinado a partir de uma tabela de recorrência de valores de TAN, <30>OX e MIN versus diferencial de impedância para condições conhecidas do fluido. A vida útil restante (RUL) pode então ser computada a partir do valor presentemente determinado de TAN, <30>AOX ou MIN. Quando a diferença de impedância corrigida para temperatura <30>Z~ TC~ alcançar 6,5 x 10,5 Ohms, o ATF é considerado a ter alcançado o fim de sua vida útil.
