Abstract

The invention provides an oil mass electronic sensor which comprises a double-tube contactless oil mass electronic sensor, a single-tube contactless oil mass electronic sensor, a chuck, a clamping seat, a one-way air valve, a central tightness adjusting screw rod, a Hall magnetic-sensing effect contactless electronic switching circuit and an electrically heated automatic temperature control voltage comparison contactless switching circuit, wherein the chuck and the clamping seat are assembled with each other and are matched with the oil mass electronic sensors; the one-way air valve and the central tightness adjusting screw rod are assembled and matched with the chuck and the centre hole of the clamping seat. The oil mass electronic sensor is reasonable in integral structure, easy to assemble and applicable to volume production, has the advantages of fewer connectors, low material consumption, light weight, high degree of automation, stable working performance, long service life and strong environmental adaptability, and is an extremely ideal oil mass detection sensor for various automobiles.

Description

technical field [0001] The invention relates to the field of oil quantity detection components which are indispensable for various oil vehicles, in particular to an oil quantity sensor. Background technique [0002] With the development of my country's automobile industry, the oil quantity sensor, the oil outlet pipe and the oil return pipe are all independent components. Their disadvantages are: many openings in the fuel tank, poor sealing, and large material consumption; and the change of the oil quantity sensor depends on the temperature in the fuel tank. The oil float is realized by changing the resistance value of the contact variable resistor with the change of the oil level. Its disadvantages are: poor contact performance, poor stability, short service life, and poor energy saving and environmental protection. [0003] With the continuous development of my country's automobile industry, the oil quantity sensor of modern vehicles such as automobiles has been developed a...
