The invention relates to the field of aircraft fuel systems, in particular to a fuel gauge testing device. The device comprises a fuel gauge, a fuel gauge connector, a power supply, a test cable, two diodes which are reversely connected in parallel, a change-over switch and seven capacitor banks, the common end of each capacitor bank is connected to the center of the two diodes which are reversely connected in parallel, and each capacitor bank is connected with the change-over switch and is used for respectively simulating the fuel quantity corresponding to each scale point of the fuel gauge and checking the fuel gauge. The fuel gauge is checked before being installed, so that the waste of working hours caused by faults due to the fact that the fuel gauge is installed without being checked and the damage of lines or finished parts caused by equipment disassembly and assembly are avoided, and the cost can be saved.
本申请涉及航空器燃油系统领域,尤其涉及一种燃油油量表试验装置。所述装置包括燃油油量表、油量表连接器、电源、测试电缆、反向并联的两二极管、转换开关和七个电容组;各个所述电容组的公共端连接在所述反向并联的两二极管的中心,且各个所述电容组与所述转换开关连接,用于分别模拟所述燃油油量表的各个刻度点对应的油量,对所述燃油油量表进行检验。对燃油油量表进行装前校验,避免了油量表不经过校验就装机造成的故障发生时的工时浪费以及拆装设备时造成的线路或成件损伤,能够节约成本。
