Model 7xS Steam Service Coaxial Guided Wave Radar Probe  |
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 coaxial probe is the most efficient of all probe configurations and should be the first consideration in all applications. Analogous to the efficiency of modern, coaxial cable, coaxial probes allow almost unimpeded movement of the high frequency pulses throughout its length.
The electromagnetic field that develops between the inner rod and outer tube is completely contained. The efficiency and sensitivity of a coaxial configuration yields robust signal strength even in extremely low dielectric (εr ≥ 1.4) applications.
The Model 7xS steam probe was designed specifically for use in saturated steam applications up to 650° F (340 C) and 2400 psi (165 bar), and is patented to accurately compensate for changing vapor space properties.
