Eclipse® Enlarged Coaxial Probes
Models 7xx-N, 7xx-P, and 7xx-R
|
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.
The Enlarged Coaxial Probe utilizes a 1.75" outer tube and 5/8" inner conductor, this new probe offers all of the performance specifications of the existing coaxial probes plus the viscosity performance of a twin rod.
This probe is designed for those relatively viscous applications, including those for interface level measurement, that have dielectric constants too low for a twin rod or single rod. It is available with coaxial probe Models 7xA, 7xD, 7xP, 7xR, and 7xT in all existing materials of construction.

Measurement Principle:
Guided Wave Radar is based upon the principle of TDR (Time Domain Reflectometry). Pulses of electromagnetic energy are transmitted down a probe. The pulse is reflected when it reaches an impedance change such as a liquid surface. The transit time is calculated and converted to level.
