The Eclipse® Model 700 Transmitter is a loop-powered, 24 VDC level transmitter that is based upon the proven and accepted technology of Guided Wave Radar (GWR). Encompassing several significant engineering accomplishments, this leading-edge level transmitter is designed to provide measurement performance well beyond that of many of the more traditional technologies.
FEATURES AND BENEFITS OF THE 700:
- Build-Up Detection – Maximize uptime and minimize maintenance costs by preventing unnecessary shutdowns
- Intelligent Technology – Improve troubleshooting with automatic Echo Curve capture
- Tank Utilization – Eliminate top of probe dead zones unlike any other GWR on the market
- True Level Measurement – Increase reliability and accuracy by measuring true product level across the entire probe length vs. inferred measurements
- Lower production risks while increasing safety and reliability, ensuring proper operation of your level measurement instrumentation
- Address the broadest range of applications across any level of complexity with ease
- Reduce commissioning time, while cutting maintenance and increasing uptime
- More reliable signal, offering additional application flexibility
This single transmitter can be used in a wide variety of applications ranging from very light hydrocarbons to water-based media. One universal Model 700 transmitter can be used and interchanged with several different probe types and offers enhanced reliability as it is certified for use in critical SIL 2/3 hardware safety loops.
The Eclipse Model 700 supports both the FDT/DTM and Enhanced DD (EDDL) standards, which allow viewing of valuable configuration and diagnostic information such as the echo curve in tools such as PACTware™, AMS Device Manager, and various HART® Field Communicators.
The Eclipse Model 700 is capable of measuring both an upper liquid level and an interface liquid level. As only a portion of the pulse is reflected from a low dielectric upper surface, some of the transmitted energy continues down the GWR probe through the upper liquid. The remaining initial pulse is again reflected when it reaches the higher dielectric lower liquid. A typical interface application would be oil over water.
CHOOSING THE PROPER PROBE
This is one of the most important decision in the application process. The probe configuration establishes fundamental performance characteristics. Eclipse Model 700 probes can be described by two basic configurations:
• Single element (rigid rod or flexible cable)
Both probe configurations have specific strengths and weaknesses. Although there can be overlap, and different probes can certainly be used in similar applications, it is important to understand their basic differences so that one can choose the probe type that will offer optimal performance.
