Eclipse® 706 guided wave radar

An Introduction to Guided Wave Radar Technology. When MAGNETROL introduced guided wave radar technology to liquid level applications for the process industry, it filled a critical need of providing exceptionally robust level measurement under challenging process conditions. Guided wave radar continues to deliver premier performance because it is virtually unaffected by density variance, as well as media conditions where turbulence, vaporization, foaming, boiling and flashing can occur.

Principle of Operation. Guided wave radar functions according to the principle of time domain reflectometry (TDR). As shown at right, a generated pulse of electromagnetic energy travels down the probe. Upon reaching the surface of the medium, the pulse is reflected. Sophisticated high speed circuitry captures these signals in real time (nanoseconds) and reconstructs them in equivalent time (milliseconds) to make level measurement a practical reality.

Unlike conventional non-contact radar, which launches its signal into free space, the ECLIPSE GWR transmitter launches its signal within the contained path of a probe (waveguide) which is in direct contact with the process media. This direct contact makes the signal less vulnerable to distortion brought on by process conditions that might challenge other technologies.

ECLIPSE transmitters have been designed for easy setup and configuration. It is a compact instrument that is easy to handle and install, and the innovative dual-compartment angled housing makes for optimum viewing of the graphic LCD.
