A review is presented of commercial oil quality sensors based on detecting changes on the dielectric constant of lubrications oils. Among the different types of commercial sensor technology, special attention is placed on dissipation factor or Tanδ sensors. Tanδ sensors are known for the effective measurement of the oil condition which makes them suitable for the variable service intervals. Tanδ sensors are widely applied in different types of machinery such as diesel and petrol engines, compressors, wind turbines, industrial gear reducers, generator sets and hydraulic systems. Furthermore, Tanδ sensors are a cost effective solution when compared to the rest of commercial oil quality sensing techniques. An electronic design procedure for Tanδ sensors based on oscillators is explained which allows customization of this technology for its use under different tribological bench test configurations. A discussion of the advantages and disadvantages of current oil quality sensor technology and the future trends are shown.
