Abstract
A sensor assembly for sensing the level and type of fuel in a reservoir is provided. The sensor assembly includes a pair of electrically conductive plates extending longitudinally between opposite ends and positioned in laterally spaced relationship with respect to one another. The pair of plates are encapsulated within a substrate of a less electrically conductive material to isolate the plates from one another and from their external environment. The substrate is of a spring-like material which is expandable and contractible in order to vary the height of the sensor assembly.
