USE OF RESILIENT SEALS FOR HIGH TEMPERATURE AND/OR HIGH PRESSURE SEALING IN A GUIDED WAVE RADAR LEVEL MEASUREMENT DEVICE

摘要

A guided wave radar level measurement device includes a process connection composed of an outer conductor and a central conductor. The central conductor is surrounded at least in part by a dielectric material. One or more resilient metal seals can be employed to form a hermetic seal around a portion of the probe. The metal seal protects the dielectric material such that the hermetic seal is isolated from process and temperature shock. The metal seal(s) can be further mated with one or more insulators and one or more gaskets, the metal seal(s) to provide a thermal and mechanical barrier as well as offering chemical resistance to the guided wave radar level measurement apparatus.
