Hornantenne mit Verbundwerkstoffstrahler

摘要

A horn antenna (210) suitable for use with a level measurement device and having a composite emitter structure. The emitter structure or assembly comprises an emitter (222) and a plug (224). The emitter (222) provides the process interface and is formed from a material having properties which include microwave transparency, chemical resistance and/or mechanical strength. The plug (224) is isolated or partitioned from the process interface. The plug (224) is formed from a material different from the emitter (222) and exhibits the properties of microwave transparency and/or mechanical strength. According to another aspect, the level measurement device includes a coupling mechanism which allows the removal of the horn antenna (210) independently of the emitter (222).
