Magnetrol eclipse 705 Safety Manual
Guided Wave Radar
Level Transmitter
SIL Certified Safety Manual for
Enhanced Model 705-51AX-XXX
Software v3.x
This manual complements and is intended to be used with the
Eclipse
®
Enhanced Model 705 Installation and Operating manual
(Bulletin 57-600 dated August 2005 or later).
Safety Function
The HART
®
version of the Eclipse
®
Enhanced Model 705
Guided Wave Radar (GWR) transmitter will measure
level and transmit a signal proportional to that level
within the stated safety accuracy of ±2% of span or the
measured error published in I/O Manual 57- 600,
whichever is greater. In addition, when continuous,
automatic diagnostics detect that the transmitter cannot
perform this function, the output will be driven to the
customer-specified out-of-range signal (i.e., less than
3.8 mA or greater than 20.5 mA).
The Enhanced Model 705 is certified for use in low or
high demand level measurement applications.
Application
The Enhanced Model 705 Guided Wave Radar level
transmitter can be applied in most process or storage
vessels, bridles, and bypass chambers up to the probe’s
rated temperature and pressure. The Enhanced Model 705
can be used in liquids, slurries or solids to meet the safe-
ty system requirements of IEC 61508/IEC 61511-1.
Benefits
• Level protection to SIL 3 as certified by exida
Certification per IEC 61508/IEC 61511-1.
• Probe designs to +800 °F (+427 °C),
6250 psig (430 bar) and full vacuum
• Cryogenic applications to -320 °F (-190 °C)
• IS, XP and Non-Incendive approvals
• Ability to measure reliably to the very top of the vessel.
(Meets TÜV: WHG 19 overfill specifications when
used with Model 7xD, 7xG, 7xR, and 7xT probes).
