Development of diode sensing devices monitoring degree of oil deterioration in real time

Type: article
Abstract: Diode-type sensors were fabricated by employing a partially anodized Ti plate and a pair of noble-metal (Pt, Pd, or Au) electrodes, and the effects of the degree of oil deterioration on the various electrical properties of the diode-type sensors were investigated in this study. The current–voltage characteristics, current-response behavior under an applied bias voltage, and conductance-response behavior were obviously dependent on the total acid number, TAN, which is a significant parameter for evaluating the degree of oil deterioration, The diode-type sensor using a pair of Pt electrodes showed large responses among all sensors. The sensor responded to proton species dissociated from ethanoic acid in oil as well as dissolved H2 in oil, which is quite important in monitoring the degree of oil deterioration.
