 Model 7xF-E Hygienic Single Rod Guided Wave Radar Probe   Printer Friendly Version
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.

The Model 7xF-E is engineered for the food & beverage, pharmaceutical, biotech and semiconductor industries.
Operating Principle Features Options Downloads
 
Guided Wave Radar is based upon the principle of TDR (Time Domain Relectometry). 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.
