  • Corrosion inhibiting switched polarity fuel level sender module
    Patent number: 5172007
    Abstract: Galvanic corrosion of the fuel sender immersed in the corrosive fuel mixture is minimized by supplying the sender with current that periodically switches polarity. The switching rate is selected to prevent or greatly minimize irreversible oxidation buildup. The vehicle body computer responds to current flow through the sender without regard to the alternating polarity drive signal. The switched polarity sender module can thus be employed without necessitating modification of the sender or body computer components.

  • Electronic circuit for fuel level sensor
    Patent number: 5050433
    Abstract: Corrosion of the fuel tank float device by electrolysis is minimized by driving the fuel level sender with short duty cycle pulses instead of a continuous current. While the fuel level sender is energized by a pulse, the analog sample and hold circuit obtains a reading from which fuel level can be determined. A synchronizing circuit controls the sequence in which the fuel level sender is energized and the reading taken, to insure that readings are taken during steady state conditions. An impedance matching circuit compensates for nonlinearities of the fuel level gauge. The impedance matching circuit includes a pair of precision resistors and a voltage multiplier circuit. The impedance matching circuit allows the moving coil fuel level gauge to be energized in a fashion which simulates a continuous current flowing between fuel level sender and gauge.
