ECLIPSE® MODEL 705 GUIDED WAVE RADAR TRANSMITTER |
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. | ||||||||||
Operating Principle 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. | ||||||||||
