Abstract: Technologies are generally described for an integrated monitoring system to monitor several operational aspects of a bearing assembly, analyze monitored aspects, provide predictions, alerts, and reports based on general equipment data or specific rotating machine data. A number of sensors in and on a bearing housing may sense a variety of operational aspects and provide input to a local or remote monitoring device. The bearing housing may include sensor mounting locations for one or more sensors. In some examples, an oil level sensor placed in a suitable mounting location on the bearing housing may detect oil levels inside the bearing housing. The monitoring device may analyze the sensor inputs in light of other information such as historic performance data, environmental information, etc. Reports, predictions, alerts, and/or suggested corrective actions may be generated based on the analysis by the monitoring device and/or remote devices communicatively coupled to the monitoring device.

Abstract: Systems and methods for particle leak detection generally include a separation or collection device configured to filter particulate from a stream and a detection device downstream of the separation or collection device. The detection device can be positioned to detect particulate that passes the separation or collection device and can include a probe configured to detect the solid particles. The particle leak detection systems can be configured to be disposed on moveable systems, such as moveable systems in coke oven operations.

Abstract: Tooling systems and methods may be employed for installing a plurality of visually similar threaded fasteners to a plurality of assemblies. Each of the assemblies may have one or more threaded mating surfaces configured to receive different types of threaded fasteners, e.g., formed of different materials. The tooling system may include a tool(s) having a drive surface configured to install a threaded fastener by relative rotation of a gripping feature of the fastener with respect to a corresponding mating thread, each tool having a sensor disposed adjacent the drive surface and configured to detect a presence of the first material when a gripping feature of the one of the threaded fasteners of the first fastener type is positioned on the drive surface. The tooling system may also include a controller configured to determine the type of the selected threaded fastener based upon the sensor.

Abstract: There is disclosed a lubricant debris monitoring system for a gas turbine engine. The system includes a magnetic chip collector having electrodes defining a gap therebetween configured to be filled with lubricant. The magnetic chip collector generates a magnetic field for attracting the debris. The system further includes a processor configured to be connected to a power source and for performing an analysis of an signal between the electrodes. The processor stores occurrences of at least one characteristic of the signal exceeding a respective threshold. The system further has a communication system communicatively connected to the processor and configured for transmitting the analysis of the signal.

Abstract: One object is to increase the amount of abrasion powder accumulated in a sensing region to improve the sensitivity in sensing the abrasion powder. Provided is a sensor for sensing reduction of electric resistance between electrodes, a magnetic field being applied between the electrodes to accumulate magnetic powder floating in a lubricant between the electrodes, wherein at least one sensing region in which the magnetic powder is to be accumulated is provided in at least a part of a region between the electrodes, and the magnetic powder is inhibited from being accumulated in a non-sensing region constituted by a space around the electrodes other than the at least one sensing region.

Abstract: The present application discloses a sensor provided with a detection portion that detects a foreign substance of a predetermined size or larger generated in a lubricant in a gear device and an output portion that, upon the detection portion detecting the foreign substance, outputs information indicating that the foreign substance has been detected.

Abstract: There is described herein methods and systems for detecting of metallic chips in a fluid system of an aircraft engine. A resistance value is measured across a magnetic chip detector mounted to a fluid system of the aircraft engine. The resistance value is transmitted to an engine computer of the aircraft engine. In the engine computer, The resistance value is compared to a first threshold and a first warning indicative of a chip in the fluid is issued when the resistance value exceeds the first threshold.
