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.
Claims12
An oil system, in particular a hydraulic system or a lubricating oil system, having a sensor (14) for monitoring the impurity content in the oil in the oil system (1), which senses a value that correlates with the impurity content, whereby the sensor is designed as a turbidity sensor (14) which measures the turbidity of the oil which occurs as a function of the impurity content, whereby the turbidity sensor (14) is situated in a feeder line (5) upstream from an equipment arrangement (6) which is supplied with and/or works with oil, characterized in that the turbidity sensor (14) is arranged upstream from a switching valve (9) in the feeder line (5), whereby the switching valve (9) in a first switch position supplies the oil to the equipment arrangement (6), and in a second switch position it supplies oil to a bypass line (11) in which is arranged an element (12) suitable for reducing the impurity content in the oil flowing through the element, whereby the turbidity sensor (14) or a controller (21) which communicates with the turbidity sensor (14) actuates the switching valve (9).
