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.

A method of controlling at least one lubrication apparatus involves: determining whether vibration associated with the at least one lubrication apparatus satisfies one of a plurality of different criteria; and controlling the at least one lubrication apparatus according to whether the vibration associated with the at least one lubrication apparatus satisfies the one of the plurality of different criteria.

A sensor transportation apparatus to convey an elongate sensor assembly through a wellbore, the sensor transportation apparatus comprises a pair of axles and a pair of wheels corresponding with the pair of axles with each wheel mounted on a respective said axle to rotate about an axis of rotation perpendicular to a longitudinal axis of the elongate sensor assembly. A protection structure extends longitudinally around each wheel to prevent a side of the wheel from contacting a wall of the wellbore. Each wheel extends above and below the protection structure to contact a side of the wellbore.

A packaged oil delivery with integral flow restrictor including a dispenser assembly and a restriction assembly. The dispenser assembly includes a dispenser that is to be mounted on a mechanical system to enhance lubrication of gears, bearings, shafts, seals, and the like. As elements of mechanical systems often rotate at high/low RPM, the channels are intended to slow/expedite the speed in which oil is passively delivered onto the aforementioned components. The restriction assembly includes channels internally disposed within the dispenser to passively meter the flow of oil being expelled. The speed with which the oil is expelled from the inside of the dispenser is directly related to the length and pattern that the channel has.
