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.

The present invention pertains to a method of determining a lubrication oil condition of a stationary gas engine comprising the steps of retrieving a lubrication oil temperature information and retrieving a lubrication oil level information from a lubrication oil level sensor, wherein the lubrication oil level sensor is a capacitance sensor, and a step of normalizing a lubrication oil level information over the lubrication oil temperature information.

A system includes one or more processors and a resonant sensor that contacts oil within an engine of a vehicle system. The sensor generates electrical stimuli at different times during an operational life of the engine. Each electrical stimulus has multiple different frequencies applied to the oil. The one or more processors receive electrical signals representing impedance responses of the oil to the electrical stimuli. The one or more processors determine a concentration of a polar analyte in the oil at the different times based on the impedance responses and calculate a degradation value for the engine based on the polar analyte concentration. Responsive to the degradation value exceeding a designated degradation threshold, the one or more processors at least one of schedule maintenance for the vehicle system, provide an alert to schedule maintenance for the vehicle system, or prohibit operation of the vehicle system until maintenance is performed.

The present invention relates to a sensing unit for monitoring the condition of a liquid, the sensing unit comprising at least one sensor and an evaluation unit. The sensing unit is adapted to measure two or more parameters of the liquid by use of at least one sensor, where the parameters relate to at least liquid degradation or wear debris particle generation. The at least one sensor is adapted to provide at least two signals, each signal providing its values in a fashion suitable for developing a mean value and a variance different from zero over a course of at least two measurements. The evaluation unit is adapted to correlate the measured signals, and to evaluate the condition of the liquid by comparing the measured at least two parameters. Thereby, a reliable monitoring system giving continual feed-back on the performance of the lubricant and the machine in an auto-correlated manner is obtained, thus allowing continual adjustments to improve uptime and machine life.

A fuel property sensor including a substrate, a first lead wire, a second lead wire, a wiring member, and a determiner. The substrate is disposed in such a position as to be in contact with the fuel. The first lead wire is connected to the substrate. The second lead wire is connected to the substrate. The second lead wire is spaced from the first lead wire. The wiring member is provided on the substrate. The wiring member connects the first lead wire and the second lead wire. The wiring member is configured to electrically disconnect the first lead wire and the second lead wire from each other by reaction with impurities contained in the fuel. The determiner is configured to determine whether the first lead wire and the second lead wire are electrically connected.

Disclosed is a monitoring apparatus for monitoring a state of wear of a component of a reciprocating piston internal combustion engine wherein an oil collection device is provided for the collection of lubrication oil from the cylinder so that a predetermined measured quantity of lubrication oil is suppliable from the cylinder to a measurement device.
