Systems and methods are provided for enabling communication, without breaching the engine firewall, between a datalogger located on one side of the firewall and one or more sensor devices that are located on the opposite side of the firewall. The systems and methods described herein can allow a transmitting node (i.e., a transmitting datalogger) to transmit collected data (from an auxiliary sensor) to a receiving node (i.e., a receiving datalogger) while reducing or minimizing various difficulties associated with addition of an auxiliary sensor in the engine environment. The transmission of data from the transmitting node to the receiving node can correspond to wired data communication or wireless data communication.

An oil blending system for a marine diesel two-stroke engine and/or generator comprises a blender having at least one inlet for receiving a lubrication oil and at least one other component and at least one outlet for outputting a mixed lubrication oil composition to the engine or generator. A blender controller is configured to receive parameter data on the current lubrication oil status used in the engine or generator and receive parameter data on the current engine and/or generator status. The blender controller is also configured to automatically determine whether the currently used lubrication oil is within a predetermined parameter range based on the current engine and/or generator status. If the current lubrication oil is outside a predetermined parameter threshold, the blender controller is configured to determine a new lubrication oil composition for the engine or generator.

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 method of lubricating a fluid production pump may include mixing a polarized lubricant with water to produce a diluted lubricant. The method may additionally include creating a flowpath within the fluid production pump. An initial volume of the diluted lubricant may be circulated within the flowpath to allow the diluted lubricant to react with components of the fluid production pump and form a protective barrier on the components of the fluid production pump. The method may further comprise repeatedly introducing a periodic volume of diluted lubricant into the fluid production pump according to a predefined lubrication schedule.

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.

Apparatuses are disclosed for machine fluid monitoring/sampling comprising a transparent sight glass attachable to a machine such that machine fluid is transferable to the sight glass. The sight glass may have an open first end, a closed second end, a sidewall, and an inside surface and an outside surface extending from the open first end to the closed second end and at least partially surrounding a cavity for the machine fluid, and one or more remote sensing ports. The one or more remote sensing ports may have a wall, an inner face, and an outer face, and may be positioned between the open first end and the closed second end of the sight glass. The material of the one or more remote sensing ports may be shaped to reduce distortion and/or increase visibility of the machine fluid relative to portions of the sight glass bordering the remote sensing ports.

Embodiments of systems and methods disclosed provide a hydraulic fracturing unit that includes a reciprocating plunger pump configured to pump a fracturing fluid and a powertrain configured to power the reciprocating plunger pump. The powertrain includes a prime mover and a drivetrain, the prime mover including a gas turbine engine. The hydraulic fracturing unit also includes auxiliary equipment configured to support operation of the hydraulic fracturing unit including the reciprocating plunger pump and the powertrain. A power system is configured to power the auxiliary equipment. The power system includes a power source and a power network. The power source is configured to generate power for the auxiliary equipment. The power network is coupled to the power source and the auxiliary equipment, and configured to deliver the power generated by the power source to the auxiliary equipment. Associated systems including a plurality of hydraulic fracturing units are also provided.

An arrangement forming a lubricant circuit includes at least one lubricant line, at least one line branching that branches the lubricant line into a first branch and a second branch. The arrangement further includes at least one lubricant reservoir integrated into the first branch, and at least one line junction where the first branch and the second branch merge. The first branch is lockable and releasable.
