1. A guided wave radar level measurement device, comprising:
a probe comprising an outer conductor and a central conductor, said central conductor surrounded at least in part by a dielectric material;
at least two metal seals that form a hermetic seal around a portion of said probe, said dielectric material protected by said at least two metal seals such that said hermetic seal is isolated from process and temperature shocks; and
at least one insulator and at least one gasket wherein said at least two metal seals are mated with said at least one insulator and said at least one gasket to provide a thermal and mechanical barrier as well as isolating electronics of said guided wave radar level measurement device from said process and temperature shocks.
