Swing rod type Hall oil level sensor

Abstract

The invention discloses a swing rod type Hall oil level sensor. The swing rod type Hall oil level sensor comprises a rotating shaft assembly, a steel wire oscillating bar, a floating ball body assembly, a magnetic steel assembly, an induction module, a circuit board shell, a flange base, a flange gasket and an end cover. An integrated embedded cavity is adopted, the induction module is embedded into an oil tank, the induction module is communicated with the atmosphere outside the oil tank and is not communicated with the interior of the oil tank, so that a non-contact structure is achieved; expandability is high, the output form of the induction module can be changed by replacing other ICs of the same series and different specifications; and later programming can be achieved by additionally arranging a single-chip microcomputer for programming intelligence.

Description

technical field [0001] The invention relates to a swing rod type Hall oil level sensor, which belongs to the technical field of oil level sensors. Background technique [0002] The fuel level sensor is installed on construction machinery with high work intensity and harsh working conditions (excavators, loaders, bulldozers, forklifts, cranes, road machinery, agricultural machinery, etc.). Its vibration intensity is very high, and the temperature of the working environment changes drastically. The manufacturer requires a long warranty period. [0003] At present, most of the widely used fuel level sensors are contact-type fuel level sensors. Electronic components such as circuit boards and sensors are in contact with fuel for a long time, which is very prone to corrosion, which affects the service life of the sensor, and has higher requirements for the application environment of the sensor. . [0004] And existing some so-called non-contact oil level sensors, though adopt c...

Problems solved by technology

[0003] At present, most of the widely used fuel level sensors are contact-type fuel level sensors. Electronic components such as circuit boards and sensors are in contact with fuel for a long time, which is very prone to corrosion, which affects the service life of the sensor, and has higher requirements for the application environment of the sensor.

[0004] However, some existing so-called non-contact fuel level sensors use a casing to encapsulate the electronic energy, but the casing still has a connection gap, and the gap is also immersed in the fuel for a long time, and there is still the possibility of oil leakage.

In addition, the output wires of electronic components still have to pass through the "information module" immersed in oil, and then pass through the sensor installation surface, leading to the outside, there is a possibility of oil leakage
