DEVICE AND METHOD FOR RECORDING CONTAMINATIONS IN A HYDRAULIC SYSTEM
First Claim
1. A contamination recording apparatus for recording contaminations in a hydraulic fluid to be examined flowing in a hydraulic system of an aircraft, having at least one conveying device, integratable in a hydraulic system, for conveying the flowing hydraulic fluid, having at least one light source for exposing the hydraulic fluid flowing in the conveying device to light, and having at least one detection device for recording a fraction of the light absorbed by the exposed hydraulic fluid, the at least one light source being formed in order to emit light having a wavelength in the near-infrared range.

Abstract
The invention relates to a contamination recording apparatus (12) for recording contaminations in a flowing hydraulic fluid (10) to be examined in aircraft (11a), which comprises a conveying device (14) for conveying the flowing hydraulic fluid (10), a light source (34) for exposing the hydraulic fluid (10) flowing in the conveying device (14) to light (46), and a detection device (36) for recording a fraction of the light (46) absorbed by the exposed hydraulic fluid (10), the light source (34) being formed in order to emit light (46) having a wavelength in the near-infrared range. The invention furthermore relates to a hydraulic system (11) equipped with such a contamination recording apparatus (12) and to an aircraft (11a), and also to a method for recording contaminations in a hydraulic fluid (10) flowing in a hydraulic system (11) of an aircraft (11a).
