Magnetically Coupled Linear Sensors Used for Fuel Level Sensing Are

Multiple Choice

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
