Eaton Corporation Plc has announced that Gulfstream Aerospace Corp. has selected Eaton's digital fuel gauging technology for its G500 and G600 business jets. In addition to delivering superior accuracy, Eaton's digital technology significantly improves reliability, safety and weight savings and is an affordable retrofit solution to update analog systems. Eaton's digital fuel quantity measurement technology is up to 40% lighter than similar analog systems and has been verified to eliminate many analog-related errors.

It also meets the Federal Aviation Administration's latest fuel-safety requirements. More precise fuel-quantity readings reduce the need to carry large volumes of extra fuel to cover for the inaccuracies of analog systems. Less fuel means less weight, which in turn improves fuel efficiency, lowers fuel costs and reduces carbon emissions. Eaton's digital technology incorporates an integrated capacitance-to-digital converter chip equipped with a built-in temperature sensing and contamination resistance measurement.

The chip eliminates the need for separate capacitance measurement circuitry, and temperature sensing helps adjust for variations of dielectric strength and density throughout the fuel tank.
