El aceite lubricante, componente vital en máquinas rotatorias, al bajar su calidad se ve afectado el ciclo de vida del motor de sobremanera, y al no lubricarse, ese ciclo de vida es nulo. El presente proyecto pretende controlar un problema frecuente en la industria de transporte; la persistente contaminación del aceite. Para el adecuado mantenimiento, ahorro de energía y capital, se deben conocer las impurezas ligadas al aceite. Adicionalmente, el conocimiento del estado del lubricante y su futuro repuesto es importante para la prevención de fallas. Este trabajo exhibe los resultados del desarrollo de un sensor capacitivo para identificar las impurezas en aceite lubricante usado en motores diésel, presentando el comportamiento eléctrico del sensor expuesto al aceite y de los agentes externos tales como agua y glicol. Los experimentos consideran la temperatura y el volumen de impurezas en un aceite en estado puro y bajo contaminantes.

Palabras Claves: Capacitivo, lubricante, sensor.



A vital component of rotary machines is the lubricating oil which quality significantly impacts on their life cycle. The present project aims to control a frequent problem in the transport industry; the persistent contamination of the oil and the lack of impurities detection on the motor lubricants. For proper maintenance, energy and capital savings, the impurities linked to the oil must be known. In addition, the status of the lubricant and its future replacement is important for failure prevention. This work presents the results of the development of a capacitive sensor to identify impurities in lubricating oil used in diesel engines, presenting the electric behavior of the sensor exposed to oil and external agents such as water and glycol. The experiments consider the temperature and the volume of impurities on both pure and contaminated oils.

Keywords: Capacitive, lubricant, sensor.
