Eclipse Model 705 for Hygienic Applications

The Enhanced Eclipse Model 705 is a loop-powered,24 VDC, level transmitter based upon the revolutionary Guided Wave Radar (GWR) technology. This 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.

Description

Technology of Eclipse Model 705 for Hygienic Applications

Eclipse Model 705 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.
