Equipment for measuring the level of fuel in a tank, comprises float attached to double contact cursor which sweeps two segmented tracks each connected to a common resistive track

摘要

A float in the fuel tank is attached to a rotating cursor which has two contacts (110,120). The cursor sweeps along two segmented (224,234) conducting tracks (220,230) which are in contact with a common resistance track (210). The two sets of segments are displaced by half a step and the common track has a resistance characteristic suited to the tank shape
