Eclipse® 706 guided wave radar transmitter

 

The Eclipse® Model 706 high performance transmitter is a loop-powered, 24 VDC level transmitter that is based upon the proven technology of guided wave radar (GWR). Encompassing a number of significant engineering accomplishments, this leading edge level transmitter is designed to provide measurement performance well beyond that of many of the more traditional technologies.

Utlilizing “diode switching” technology, along with the most comprehensive probe offering on the market, this single transmitter can be used in a wide variety of applications ranging from very light hydrocarbons to water-based media.

The innovative angled, dual compartment enclosure is now a common sight in the industry. This enclosure, first brought to the industry by Magnetrol® in 1998, is angled to maximize ease of wiring, configuration, and viewing of the versatile graphic LCD display.

One universal ECLIPSE Model 706 transmitter can be used and interchanged with all probe types, and offers enhanced reliability as it is suitable for use in critical SIL 2/3 Certified  safety loops.

The ECLIPSE Model 706 transmitter supports both the FDT/DTM and enhanced DD standards, which allows 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.

Guided wave radar

Technology

Micropower impulse radar (MIR) combines time domain reflectometry (TDR), equivalent time sampling (ETS), and modern low power circuitry. This synthesis of technologies creates a high-speed Guided Wave Radar (GWR) transmitter. The electromagnetic pulses are propagated via a waveguide that focuses the energy and yields a system many times more efficient than Non-Contact Radar.

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.

The ECLIPSE guided wave radar transmitter is based upon the technology of TDR (time domain reflectometry). TDR utilizes pulses of electromagnetic energy transmitted down a wave guide (probe). When a pulse reaches a liquid surface that has a higher dielectric constant than the air (εr = 1) in which it is traveling, a portion of the pulse is reflected. The transit time of the pulse is then measured via ultra speed timing circuitry that provides an accurate measure of the liquid level. The transit time of the pulse is then measured via high speed timing circuitry that provides an accurate measure of the liquid (or solids) level.
