The Enhanced Eclipse^® Model 705 is a 24 VDC loop-powered transmitter based upon the revolutionary guided wave radar (GWR) technology. This single transmitter can be used with all probe types and offers enhanced reliability, as demonstrated by a Safe Failure Fraction of 91%, allowing it to be used in SIL 3 loops.

This ECLIPSE guided wave radar transmitter is designed to provide measurement performance well beyond that of many traditional technologies. The innovative, patented enclosure is a first in the industry orienting both wiring and electronics compartments in the same plane; and, angled to maximize ease of wiring, configuration and data display.

The ECLIPSE Model 705 transmitter supports the FDT/DTM standard, and a PACTware? PC software package allows for additional configuration and troubleshooting flexibility.

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. An 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.
