Description

Technical Field

[0001] This utility model relates to the field of lubricating oil level sensors, and in particular to a lubricating oil level sensor with an integrated filler port function. Background Technology

[0002] A liquid level sensor is a pressure sensor that measures the liquid level. A hydrostatic level transmitter is based on the principle that the hydrostatic pressure of the measured liquid is proportional to the height of the liquid. Engines need to be filled with lubricating oil to provide lubrication, heat dissipation, cleaning, vibration damping and other functions for engine bearings, accessory gearboxes and other components. In order to ensure that the engine can run well, the lubricating oil level in the oil tank needs to be accurately measured to avoid insufficient or excessive lubricating oil in the oil tank.

[0003] Current lubricating oil level sensors are cumbersome to use during refueling, and because they are fixed and cannot be moved according to the amount of lubricating oil added, the accuracy of lubricating oil monitoring is reduced. To address these issues, we propose a lubricating oil level sensor that integrates a filler port function. Utility Model Content
