오일필터 일체형 엔진오일퇴화감지센서 시작품 개발II

The Prototype Development II of an Engine Oil Deterioration Sensor Installed Inside an Oil Filter

In this paper, it is described how the problems appeared at the previous proto type sensor are improved. As changing the pressure and temperature of engine oil in a test rig, the modified sensor is tested. Then, the measured results of capacitance and the corresponding dielectric constants under various temperatures and pressures are shown. It turns out that the electrical signal gotten from the electrodes of newly developed sensor can be more stable under the various operating conditions.
