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.

A method of distributing oil to a component within a gas turbine engine includes directing a first oil flow from an oil source to an engine component and back to the oil source, directing a second oil flow from the oil source to a generator driven by the engine and back to the oil source, monitoring a parameter of the second oil flow downstream of the generator and upstream of the oil source, detecting a contaminant in the second oil flow based on the parameter, and reducing the second oil flow to the generator when the contaminant is detected without reducing the first oil flow to the engine component. A shared oil system for a component of a gas turbine engine and a generator driven by the gas turbine engine is also discussed.

A magnetic device for capturing metal wear particles in suspension in a lubrication fluid, the magnetic device being for inserting in a straight-line insertion direction of the magnetic device into a wall of a casing via a through orifice serving to put an inside volume of the casing containing the lubrication fluid into communication with an outside volume outside the casing, the magnetic device presenting a longitudinal axis X, the longitudinal axis X being for putting into coincidence with the direction for inserting the magnetic device into the casing, the magnetic device comprising a permanent magnet suitable for attracting the metal particles and a, presence-detector member for detecting the metal particles attracted by the permanent magnet.

There is disclosed a tool for filtering a lubricant to meet a target ISO cleanliness code. The tool includes a skid-mounted integrated filtration system having a pump that circulates a flow of lubricant from an inlet port, through a heater, through a series of specifically sized filters, and past a digital particle counter. The filtration system also includes a user interface and a programmable logic controller (PLC) configured to track outputs from the pump, the oil heater, and the particle counter to monitor a cleanliness of the circulating lubricant. The filtration system also includes a filtration operations server in communication with the PLC and configured to implement a tracking and monitoring software application enabling control of the filtration system from the system itself or remotely through one or more remote user terminals such as a smartphone, a laptop or tablet computer, and the like. Other embodiments are disclosed.

One object is to provide an industrial device in which abrasion powder (conductive substance) can accumulate on a sensor to an amount necessary for proper failure prediction. An industrial device according to an embodiment of the present invention includes: a lubricant reservoir portion including a region in which a lubricant circulates; and a sensor including a pair of electrodes disposed in the region in which the lubricant circulates, the sensor being configured to sense variation of electric resistance between the pair of electrodes.

The present invention provides an abnormality detector for a rolling bearing including an outer race, and an inner race. The abnormality detector includes a filter configured to prevent metal pieces contained in lubricating oil flowing through the bearing space between the outer and inner races from passing through the filter, while allowing the lubricating oil to pass through the filter so as to flow to the outside space of the bearing space; an electric circuit including a pair of permanent magnets mounted, as a pair of electrodes, to the filter so as to be spaced apart from each other, and lines extending from the respective electrodes to a power source; and an output detector configured to detect a change in electrical output from the electric circuit when metal pieces adhere between the pair of permanent magnets, thereby detecting the state of metal pieces contained in the lubricating oil.
