TANK SEAL FOR GUIDED WAVE RADAR LEVEL MEASUREMENT

摘要

A microwave level gauge 17 for measuring a level of a process material in a tank includes a ceramic seal 316 and a microwave conductor 218. The ceramic seal 316 is disposed adjacent to an opening in the tank and adapted to isolate circuitry 203 from the process material. The microwave conductor is electrically coupled to the circuitry and extends through the hermetic seal 316 and into the process material in the tank. The ceramic seal 316 and an isolating adapter 328 cooperate to isolate the microwave conductor from the process fluid and from external forces.
