Fuel sensor, fuel measurement system and aircraft

Abstract

The invention discloses a fuel sensor, a fuel measurement system and an aircraft with the fuel sensor. The fuel sensor comprises an end cover, a chip, an electrode assembly, two probe components and two seal components; the end cover comprises a mounting plate and a connecting end and a containing end which are arranged at the two ends of the mounting plate respectively, a mounting cavity is formed in the connecting end, and a containing cavity is formed in the containing end; the chip is installed in the containing cavity; the electrode assembly comprises two plate type electrodes which are arranged in a parallel and opposite mode, and the plate type electrodes are partially contained in the mounting cavity; the mounting plate is provided with at least two through holes communicated with the mounting cavity and the containing cavity, one end of each probe component is contained in the mounting cavity and connected to one plate type electrode, and the other end of each probe component penetrates through one through hole to be connected with the chip; a gap between each probe component and the hole wall of the corresponding through hole is filled with the corresponding seal component. According to the technical scheme, the siphon phenomenon can be prevented, and the chip is not likely to be subjected to a short circuit or failure.

Description

technical field [0001] The invention relates to the technical field of aircraft, in particular to a fuel quantity sensor, a fuel quantity measuring system using the fuel quantity sensor and an aircraft using the fuel quantity sensor. Background technique [0002] The fuel quantity sensor that existing aircraft adopts is capacitive sensor mostly, and this capacitive sensor usually comprises end cap, and the lower end of this end cap is a connection end, and capacitive tube is installed, and this end cap upper end is accommodating end, and chip is installed. [0003] Capacitive sensors are generally installed obliquely and vertically inside the fuel tank. Detection components need to be installed at the end cap. There will be a matching gap where the detection components are installed. Siphon phenomenon is easy to occur at this place, and the water contained in aviation kerosene will move upward. Entering into the accommodating end of the end cap, the chip is prone to short ci...
