摘要： A contamination level determination system for hydraulic oil is provided with a pilot filter arranged in a line of a hydraulic circuit of a hydraulic working machine to remove, from the hydraulic oil, foreign matter of particle sizes that may cause an operation failure of the hydraulic working machine. A first light-blocking sensor senses passage of foreign matter on an upstream side of the pilot filter. A second light-blocking sensor senses passage of foreign matter on a downstream side of the pilot filter. An onboard controller unit functions to determine a frequency of sensing of foreign matter by the first light-blocking sensor, to determine a frequency of sensing of foreign matter by the second light-blocking sensor, and to determine a contamination level on the upstream side of the pilot filter on the basis of results of the determinations from both sensors.
