A system and method employing wear debris sensors to monitor the operation of a lubricated mechanical system such as a gearbox (e.g., in a wind turbine), a transmission or an engine in order to control operation of the gearbox in order to reduce damage and/or extend the useful life of the gearbox.

A system and method for automatic oil exchange service for electric vehicle gearboxes. The system and method includes a mechanism for monitoring and reporting status of the oil change in the gearbox. This ensures that each oil change is kept track of, that the oil is the correct grade, and that the vehicle ends up with oil that has maximum properties, avoiding contamination and improving the life of the gearbox. The present invention may be integrated directly at the same place as an electric vehicle charging station, supercharger station, or at any battery swap station.

A system for monitoring lubrication of a drive train, including a lubricant pressure sensor operable to detect a pressure of the lubricant in the drive train and configured to provide a lubricant pressure signal; lubricant volume sensor operable to detect a volume of the lubricant in the drive train and configured to provide a lubricant volume signal; non-contact temperature sensor operable to detect a temperature of the drive train and configured to provide a non-contact temperature signal; and logic management system in communication with the lubricant pressure sensor, the lubricant volume sensor, and the non-contact temperature sensor; the logic management system being configured to receive and process the lubricant pressure signal, the lubricant volume signal, and the non-contact temperature signal; wherein when the lubricant pressure signal reaches a predetermined minimum pressure level and the lubricant volume signal reaches a predetermined minimum volume level, the logic management system displays non-contact temperature measurement data to a display device.

A vehicle includes: an interrupter including a first connector connected to a driving source, a second connector connected to a transmission, and a fluid in a gap between the first and second connectors; and processing circuitry. The processing circuitry receives flowability information indicating a value related to flowability of the fluid. The processing circuitry determines whether or not a predetermined power interruption condition is satisfied. When the above condition is satisfied, and the processing circuitry determines that the value is less than a predetermined reference value, the processing circuitry controls the speed change actuator to set the transmission to a first gear stage. When the condition is satisfied, and the processing circuitry determines that the value is not less than the reference value, the processing circuitry controls the speed change actuator to set the transmission to a second gear stage having a lower reduction ratio than the first gear stage.

A fluid filtration system may include a fluid filter assembly that includes a filter element configured to filter a fluid and a sensor probe incorporated into the fluid filter assembly. The sensor probe may include a chemically reactive material sensitive to at least one property of the fluid and at least a portion of the sensor probe may be exposed to the fluid.

A hydraulic circuit includes a hydraulic pump configured to supply lubricating oil, a resisting apparatus configured to maintain an oil pressure of the lubricating oil supplied from the hydraulic pump, an oil supply channel configured to guide the lubricating oil from the hydraulic pump to the resisting apparatus, and an optical detector configured to measure a degree of contamination of the lubricating oil flowing through the oil supply channel.

A fluid condition monitoring device includes a sensing assembly including a sensor and a transducer, the sensor to sense a property of the fluid and the transducer to apply a test signal to the fluid and receive a return signal from the fluid; a control assembly coupled to the sensing assembly, the control assembly including a controller and an input/output interface, the controller interfacing with the transducer to generate fluid condition information in response to the return signal; and an interface assembly coupled to the control assembly, the interface assembly including a connection to the input/output interface to transmit the fluid condition information to an external system.

A system and method for debris particle detection with adaptive learning are provided. The method includes receiving oil debris monitoring (ODM) sensor data from an oil debris monitor sensor and fleet data from a database, detecting a feature in the ODM sensor data, generating an anomaly detection signal based on detecting an anomaly by comparing the feature in the ODM sensor data to a limit defined by system information stored in the fleet data, selecting a maintenance action request based on the anomaly detection signal, and adjusting one or more of the feature, the anomaly, the limit, and the maintenance action request by applying an adaptive learning algorithm that uses the ODM sensor data, fleet data, and feedback from field maintenance of one or more engines that evolves over time.

Disclosed is an apparatus for in-situ filtering and monitoring of a lubricating fluid which includes, among other elements, a housing, a filter assembly and a lubrication monitoring module. The housing is adapted for being secured directly to a source of lubricating fluid and defines an internal filter chamber. The filter assembly is positioned at least partially within the internal filter chamber of the housing and the lubrication monitoring module is in fluid communication with the internal filter chamber of the housing. The filter assembly and the lubrication monitoring module are arranged so as to create first and second flow paths for lubricating fluid within the housing. The first flow path directs a portion of the lubricating fluid from the source, through the filter assembly where it is conditioned and returned to the source. The second flow path directs a second portion of the lubricating fluid from the source to the lubrication monitoring module and subsequently it is returned to the source.
