Magnetrol 705 Guided Wave Radar

Magnetrol Guided Wave Radar is based upon the principle of TDR (Time Domain Reflectometry). Electromagnetic energy pulses are transmitted down a probe, when it reaches a liquid surface the pulse is reflected.

The Magnetrol Eclipse Model 705 is a two-wire, loop-powered, 24V DC liquid level transmitter based on Guided Wave Radar (GWR) technology. The Magnetrol Model 705 can be used with coaxial, twin rod and single rod probes. This leading-edge transmitter is designed to provide measurement performance well beyond that of many traditional technologies.
