Abstract
A sensor assembly is provided for determining the level of liquid, such as fuel, in a tank such as a motor vehicle fuel tank. A mounting bracket has a support end adapted to be supported from the tank and also has a distal connection end. A liquid level sensor has lower and upper ends and a resistor element extending therebetween, and is connected to the connection end of the mounting bracket by a shaft. A torsional spring is disposed around the shaft, and biases the liquid level sensor from a retracted position and toward a deployed position. In the retracted position, the sensor assembly is insertable through an access hole in the tank. In the deployed position, the upper end of the liquid level sensor is disposed generally above the shaft and the resistor element is disposed generally vertically to provide the greatest resolution possible with both linear and angular sweep floats.
