Magnetically coupled linear sensors used for fuel level sensing are being discussed. Technician A says a magnet is attached to the float arm and when the magnetic field passes the comb, the fingers are pulled against the resistor card contacting resistors that represent the various levels of fuel. Technician B says different contact sites on the strip produce different resistances that are used to determine the fuel level. Who is correct?
A) Technician A only
B) Technician B only
C) Both Technician A and B
D) Neither Technician A nor B

Question

Quizplus · Accepted Answer

Both Technician A and B are correct. Technician A describes the mechanism of how the magnetic field from the magnet attached to the float arm interacts with the comb to indicate fuel levels, while Technician B explains how these interactions at different contact sites on the strip produce varying resistances, which are then used to determine the fuel level.
