Abstract
Apparatuses and methods for fuel level sensing are described herein. An example sensor includes a sealed housing comprising a first end, a second end, and an interior defined by walls extending therebetween. The sensor includes a float surrounding an exterior of the sealed housing and is configured to move longitudinally along the sealed housing between the first end second ends. The float may include a magnetic element configured to provide a magnetic field. The sealed housing may include an electrically conductive spring coupled to at least one of the first end or the second end, and may include a ferrous element coupled to the electrically conductive spring and configured to be displaced relative to the sealed housing based on the magnetic field. The electrically conductive spring may expand and retract to adjust a resistance of the electrically conductive spring in response to the ferrous element being displaced.
