Oil tank oil level sensor

Abstract

The invention discloses an oil tank oil level sensor. The oil tank oil level sensor comprises an oil tank, the inner part of the oil tank is provided with an inner cylinder, the bottom of the inner cylinder is connected with an upright column through a spring, the two sides of the upright column are provided with grooves, the inner parts of the grooves are movably connected with floats, and the floats are positioned on the two sides of the upright column, the surface of a measuring rod is provided with an induced magnet, and the position of the induced magnet corresponds with the floats. By arranging a spring in the oil tank oil level sensor, the stability of the sensor is improved, and the ability to resist outside interference is strong. By the arrangement of the grooves, when the floats move up and down, the floats also perform circumferential movement, and then the induced magnet on the surface of the measuring rod coordinates with the floats, the floating of the floats on the surface of the upright column makes the floats sense the height of the oil level in the oil tank. The oil tank oil level sensor has the advantages of simple and novel structure, convenient installation and strong ability to resist outside interference, is suitable for popularization, and therefore better understanding of the height of the oil level in the oil tank is achieved.

Description

technical field [0001] The invention relates to the technical field of fuel tank oil level sensors, in particular to a fuel tank oil level sensor. Background technique [0002] The fuel tank sensor currently on the market consists of a column with a number of reed tubes evenly distributed along the height direction inside the column. There is a float outside the column, and a number of magnets are evenly distributed on the float. Relying on the induction between the magnet and the reed tube The height of the side child outlet liquid level. The oil quantity sensor of this fuel tank has a relatively simple structure and relatively reliable performance. However, since the float may rotate in a circumferential direction during the process of moving up and down, although many pairs of magnets can be set on the float, it will still affect the reed tube. The induction of the sensor produces deviations, which eventually causes errors in the liquid level height measured by the fuel ...
