Actual condition monitoring of engine oil through an intelligent multi-functional sensing approach
D.M.G. Preethichandra, Katsunori Shida · 2002
A multifunctional sensor is designed to measure viscosity, cleanness, temperature and capacitance of engine oils to make a clear decision on its condition. The simple structure helps easy fabrication and low cost while measuring four parameters by one sensor. The operation is described theoretically and is supported by experimental data.
