Patent
·
OSTI ID:6466090
A height sensor is provided in a vehicle leveling system having an air spring including a pressurized chamber connected between sprung and unsprung vehicle masses. Two radioactive material sources located within the chamber and attached for movement with the unsprung mass emits beta radiation which passes through the wall of the chamber and a pair of beta detectors outside the chamber and mounted on the sprung mass for movement therewith detects the beta radiation to determine the relative spacing of the sprung and unsprung masses.
