Eclipse® Model 706 High Performance Guided Wave Radar Level Transmitter for Hygienic Applications DESCRIPTION Measures Level and Volume The Eclipse® Model 706 High Performance Transmitter is a loop-powered, 24 VDC level transmitter that is based upon the proven and widely accepted 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. Utilizing patented “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. Offered in a deep-drawn 304 ss enclosure for hygienic industries, the housing is angled to maximize ease of wiring, configuration, and viewing of the versatile graphic LCD display. One universal Model 706 transmitter can be used and interchanged with all probe types, and offers enhanced reliability as it is certified for use in critical SIL 2 hardware safety loops. With the use of a unique adapter, the model 706 transmitter can even operate with older hygienic GWR probes. The Eclipse Model 706 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. APPLICATIONS MEDIA: Liquids, solids, or slurries; hydrocarbons to water-based media (Dielectric Constant εr = 1.2–100) VESSELS: Most process or storage vessels up to rated probe temperature and pressure. CONDITIONS: All level measurement and control applications including process conditions exhibiting visible vapors, foam, surface agitation, bubbling or boiling, high fill/empty rates, low level and varying dielectric media or specific gravity.

• Multivariable, two-wire, 24 VDC loop-powered transmitter for level, interface, volume, or flow. • Diode switching technology offers best-in-class signal strength and signal-to-noise ratio (SNR) resulting in enhanced capability in difficult applications. • Level measurement not affected by changing media characteristics. • No need to move levels for calibration. • Can measure reliably from the tip of the probe to the top of the vessel. • 4-button keypad and graphic LCD display allow for convenient viewing of configuration parameters and echo curve. • Proactive diagnostics advise not only what...

PROBE OVERVIEW The description below contains facts relating to the physics of GWR technology and are not specific to AMETEK LMS or to the Eclipse Model 706. SINGLE ROD PROBES Single element GWR probes operate quite differently from the typical GWR coaxial design. With only one conductor to work with, the pulses of energy develop between the single rod probe and the mounting nut or flange. In other words, the pulse propagates down and around the rod as it references its ground at the top of the tank. The energy and efficiency of the pulse are directly related to how much metallic surface exists...

TECHNOLOGY PRINCIPLE OF OPERATION Eclipse Guided Wave Radar 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 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 high speed timing circuitry that provides an accurate measure of the liquid (or solids) level. The amplitude of the reflection depends on the dielectric constant of the product. The higher...
