A method and a system for monitoring a mechanical system, the mechanical system including a lubrication system provided with a reservoir containing a lubricating liquid, with a lubrication circuit designed to lubricate the mechanical system, as well as with a particle detection device arranged in the lubrication circuit. The detection device makes it possible, in particular, to count the number of particles flowing through the lubrication circuit and/or the flow rate of the particles. Comparing that number or that flow rate with a first threshold makes it possible to determine a risk of damage affecting the mechanical system and to anticipate the maintenance or reinforced monitoring operations that possibly need to be performed.

Systems and methods for determining, using service component authenticity detection contained in a sensor module, whether an authorized or genuine service component element is installed in an automotive system are described. The authorized service component determination may be based on close-range communication technology such as radio frequency identification (“RFID”) technology. An antenna in the sensor module may read the tag information from installed service component elements in a nearby service component and send any detected information into a filtration monitoring system. The filtration monitoring system or a remote diagnostic system analyzes the returned data (or absence thereof) to determine if a genuine (i.e., authorized, OEM approved, etc.) service component element is installed or not.

A fitting for a lubrication point of a device to be lubricated and a connector for removably connecting to such fitting to provide a lubricant from a lubrication device via the fitting to the device to be lubricated are disclosed. The fitting comprises an integrated circuit for providing an identification code to identify the fitting, and a first electrical contact for establishing an electrical path between the integrated circuit and a processor of the connector when a connection between the fitting and the connector is established. The connector comprises the processor and a second electrical contact for establishing the electrical path. The integrated circuit is adapted for transmitting data, including the identification code, via the first electrical contact to the processor.

A method for monitoring a fluid system for lubricating a mechanical system. The fluid system comprises a spraying circuit connected to a main fluid circuit and to a back-up fluid circuit. The back-up fluid circuit comprises a back-up check valve closed in a nominal operating mode. The method comprises a monitoring phase comprising the generation of a first alert in the presence of the detection of a malfunction making the main fluid circuit inoperative and the back-up check valve in an open state and the generation of a second alert different from the first alert in the presence a malfunction and the back-up check valve in a closed state.

A device for outputting a future state of a central lubrication system includes at least one sensor for recording a parameter of the central lubrication system, a processing unit for processing the recorded parameter, determining a current state of the central lubrication system based on the processed parameter, and estimating a future state of the central lubrication system over a certain period of time based on the current state and stored data, and an output unit for outputting the future state of the central lubrication system.

An optical operating fluid detector for optical detection of operating fluid for a hand-guided garden, forestry and/or construction machining appliance includes a light source, an operating fluid line and a light receiver. The light source is designed for radiation of rays of light. The operating fluid line is designed for optical interaction of rays of light from the light source with operating fluid in line for the optical detection of operating fluid. The light receiver is designed for differing reception of rays of light from the line in dependence on the presence or the absence of operating fluid in the line. The operating fluid detector has an optical deflecting device. The deflecting device is designed for deflection of rays of light from the light source to the operating fluid line and/or for deflection of rays of light from the line to the light receiver. The operating fluid line is designed for differing diversion of rays of light from the light source in dependence on the presence or the absence of operating fluid in the line for optical detection of operating fluid.

To monitor oil quality of an automotive vehicle, a sensor generates a signal indicative of a characteristic of the oil. A processor is configured to determine the oil quality from the signal. A communication component transmits an indication of whether the determined oil quality meets an unacceptability criterion to an external device.

An industrial machine including a sensor and a controller. The sensor is configured to sense a characteristic of a fluid of the industrial machine. Wherein the characteristic is indicative of a contaminant level. The controller has an electronic processor and a memory. The controller is configured to receive a signal from the sensor indicative of the contaminant level, compare the contaminant level to a threshold, and upon the contaminant level crossing the threshold perform at least one selected from a group consisting of output an alert, and commence a shutdown procedure of the industrial machine.

An oil state detection device includes an index member, a lighting device that illuminates the index member, and a photographing device that photographs the index member through oil in a machine device.
