Eclipse® 705系列高性能导波雷达液位计
Eclipse®增强型705是采用具有革命性的导波雷达(GWR)技术，两线制, 24VDC回路供电的液位变送器。这个单一的变送器可以用于所有类型的探杆，并提供更强的可靠性，正如SFF=91％的安全失效系数所表现的，允许它在SIL 3回路中使用。
ECLIPSE导波雷达液位计的设计提供了远远超过许多传统技术的测量性能。该产品在工业上首次采用了先进的专利外壳设计，它是把接线室和电子线路室分别安装在同一个平面上，最优化的倾斜角度更方便接线、组态和观察显示。
ECLIPSE 705变送器支持FDT/DTM标准与PACTware™PC端软件可以允许额外的配置和灵活的故障排除。
导波雷达
低功耗脉冲雷达 结合了时域反射原理 、等效采样(ETS)与现代化低功率电路等技术。这些原理与科技的集成创造了高速导波雷达 液位计。电磁脉冲通过导波管传播，它聚焦于能量，并产生比非接触式雷达更有效的系统。

Guided Wave Radar Probes
Choosing the proper guided wave radar (GWR) probe is the most important decision in the application process. The probe configuration establishes fundamental performance characteristics. Coaxial, twin element (rod or cable) and single element (rod or cable) are the three basic configurations used today, each with specific strengths and weaknesses.
Single element GWR probes act quite differently from coaxial and twin element designs. The pulses of energy develop between the center rod and the mounting nut or flange; the pulse propagates down the rod as it references its ground at the top of the tank. The efficiency of the pulse "launch" is directly related to how much metallic surface exists around it at the top of the vessel.
Signal transmission can be significantly improved by placing a single rod inside of a bridle or chamber.
工作原理
ECLIPSE导波雷达变送器是基于TDR技术。（时域反射原理）TDR利用导波（探杆）传播电磁脉冲信号。当脉冲到达介电常数高于其行进的空气（εr= 1）的液体表面时，一部分脉冲被反射。通过超高速计时电路来精确测量信号传输的时间，从而实现对液位（固体料位）的精确测量 更多导波雷达产品
