Description

Technical Field

[0001] This utility model relates to the field of workpiece cleaning technology, specifically to an automatic cleaning device for liquid level sensor components. Background Technology

[0002] The working principle of a capacitive level gauge is to convert the position change of the measured object into capacitance for measurement. For example, the utility model patent CN223470697U discloses a capacitance measurement structure for a three-segment capacitive LNG level sensor, including an outer tube and an inner tube. The inner tube has three segments, with adjacent segments connected by an intermediate insulating component. The outer tube, in particular, is made of stainless steel and requires ultrasonic cleaning before assembly to remove contaminants such as grease, dust, metal shavings, fingerprints, and oxides adhering to the steel pipe during machining, storage, and transportation. This is to prevent affecting the stability of the capacitive field, which could lead to measurement drift, decreased sensitivity, or insulation failure. Although ultrasonic cleaning tanks can meet the cleaning requirements, loading and unloading are mostly done manually, lacking supporting automated equipment, making it difficult to apply to mass production.
