Abstract
Apparatus and associated methods relate to suppressing electrical arcing within a fuel tank in which a fuel density sensor is located by isolating electronic components of the fuel density sensor within a cavity surrounded by a dielectric housing. The dielectric housing physically isolates the sensor electronics from fuel in the fuel tank via a fuel barrier. The dielectric housing electrically isolating the sensor electronics within the cavity from potential high voltage hazards outside the cavity. Light energy optically from a first environment outside the cavity is transmitted through the dielectric housing to a second environment within the cavity to provide operating power for the sensor electronics. The light energy is converted into DC electrical energy within the cavity. A light signal indicative of fuel density is optically transmitted from the second environment within the cavity through the dielectric housing to the first environment outside the cavity.
