GWR Level Transmitter (Level Control)
Eclipse Enhanced Model 705 GWR – Guided Wave Radar Level Technology
Magnetrol‘s ECLIPSE Guided Wave Radar is based upon the technology of TDR (Time Domain Reflectometry). TDR utilizes pulses of electromagnetic energy transmitted down a probe. When a pulse reaches a surface that has a higher dielectric than the air/vapor in which it is traveling, the pulse is reflected. Ultra high-speed timing circuit precisely measures the transit time and provides an accurate level measurement. ECLIPSE GWR can be utilized to detect overall level or interface level, and when used with a HART® splitter, it can transmit two 4–20 mA signals.
The Enhanced Eclipse® Model 705 is a loop-powered, 24 VDC, level transmitter based upon the revolutionary Guided Wave Radar (GWR) technology. This GWR level transmitter offers enhanced reliability, as demonstrated by a Safe Failure Fraction of 91% (suitable for SIL2 applications). This ECLIPSE transmitter is designed to provide measurement price/performance well beyond that of all traditional technologies. ECLIPSE supports the FDT/DTM standard and a PACTware™ PC software package allows for additional configuration and trending flexibility.
