Eclipse® 705 guided wave radar transmitter

The Enhanced Eclipse® Model 705 is a 24 VDC loop-powered transmitter based upon the revolutionary guided wave radar (GWR) technology. This single transmitter can be used with all probe types and offers enhanced reliability, as demonstrated by a Safe Failure Fraction of 91%.

The ECLIPSE guided wave radar transmitter is designed to provide measurement performance well beyond that of many traditional technologies. The innovative, patented enclosure is a first in the industry orienting both wiring and electronics compartments in the same plane; and, angled to maximize ease of wiring, configuration and data display.

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.

  • Low dielectric measurement capability (εr ≥ 1.4)
  • Volumetric output
  • Quick connect / disconnect probe coupling
  • Operates in visible vapors and ignores most foams
  • IS, XP, and Non-Incendive approvals
  • Ignores coating buildup

Options

  • Foundation fieldbus™ or Profibus PA
  • Display/Keypad
  • Local Remote Mounting
  • Interface Measurement

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.

Ultrasonic pulses are emitted from the transducer, and the time required for the echo to reflect from the liquid surface and return to the transducer is measured.
