Sensor of oil burning pump

Abstract

The invention discloses a sensor of an oil burning pump. The sensor comprises a shell and a floater rod component which is hinged to the shell, a first resistance sheet and a second resistance sheet are arranged on the shell, are in parallel connection with each other and then are electrically connected with an input lead, an electric connection end of the floater rod component is provided with afirst reed which is used for being in contact with the first resistance sheet and a second reed which is used for being in contact with the second resistance sheet, and the first reed and the second reed are in parallel connection with each other and then are electrically connected with an output lead. Compared with the prior art, the sensor of the oil burning pump has the advantages that the tworesistance sheets and the two reeds are arranged, under the situation that the height difference of the upper surface and the lower surface of the inner side of an oil tank and the rotation radius ofthe floater rod component are fixed, the number of resistance values which can be provided by the sensor of the oil burning pump is far higher than that of resistance values provided by a sensor of atraditional oil burning pump, and the sensor of the oil burning pump is extremely suitable for design of a flat oil tank sensor and has a great advantage in meeting the demand of a meter for precise display.

Description

technical field [0001] The invention relates to the technical field of fuel level sensors, in particular to a fuel pump sensor. Background technique [0002] Such as figure 1 A schematic structural diagram of a fuel pump sensor in the prior art is shown, and the fuel pump sensor is mainly composed of a float rod assembly 1 ′, a resistor plate 2 ′ and a reed 3 ′. When the oil level changes, the float rod assembly 1' of the fuel pump sensor will rotate, and this rotation will drive the contact on the reed 3' to slide on the resistance sheet 2', and then produce different resistance values ​​to output to meter. However, with the use of automobiles, consumers have put forward certain requirements for accurate display of oil quantity on instruments. The position displayed by each meter has a unique resistance value corresponding to it in the oil pump sensor. If the display accuracy of the meter is improved (regardless of the influence of the meter itself), more resistance valu...
