Abstract
The invention relates to an oil system, in particular a hydraulic oil system or a lubricating oil system, comprising a sensor for monitoring the impurity content of the oil in the oil system, the sensor detecting a value which is correlated with the impurity content. A particularly cost-effective construction is achieved, if the sensor is configured as a turbidity sensor which measures the turbidity of the oil, which has been caused by the impurity content.
