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

Device and method for recording contaminations in a hydraulic system

Diagnostic system including a sensor device with a sensor for generating signals corresponding to a first operational condition, a control device with a timer and function for performance of measurements, and a signal transmission device. The system includes a device for determination of a second operational condition of the system component and configured where the sensor value of the signal transmission device corresponding to the first operational condition is furnished when the sensor value corresponding to a second operational condition of the transmission mechanism is higher or lower than a comparative value, and housing component of a lubricant container and a closure device for sealing an opening of the housing component from a lubricant present in the operational use thereof in an internal space thereof, having arranged therein: at least one sensor device including at least one sensor for determining the water content in the lubricant.

Diagnostic system and diagnosing method, housing component of a lubricant container

The invention relates to a housing part containing a lubricant reservoir and at least one respective inlet and outlet opening for filling and draining a lubricating fluid into and from the lubricant reservoir. The inlet and outlet openings are sealed by releasable closure devices each comprising a sensor means for determining the operation parameters in a lubricant contained in the lubricant reservoir and for generating and/or storing sensor signals, as well as a transceiver for the transmission of the sensor signals to an external processing unit.

Closing device, housing part of a lubricant container, diagnostic system and diagnostic method for monitoring the operating state of a lubricant in the housing part

Diagnostic system including a sensor device with a sensor for generating signals corresponding to a first operational condition, a control device with a timer and function for performance of measurements, and a signal transmission device. The system includes a device for determination of a second operational condition of the system component and configured where the sensor value of the signal transmission device corresponding to the first operational condition is furnished when the sensor value corresponding to a second operational condition of the transmission mechanism is higher or lower than a comparative value, and housing component of a lubricant container and in particular closure device for sealing an opening of such a housing component from a lubricant which is present in the operational use thereof in an internal space thereof, having arranged therein: at least one sensor device comprising at least one sensor for determining the water content in the lubricant.
