SIL Certified Safety Manual for
Eclipse
®
Model 706-512X-XXX
High Performance Guided Wave
Radar Level Transmitter
This manual complements and is intended to be used with the
Magnetrol
®
Eclipse
®
Model 706 High Performance Guided Wave
Radar Installation and Operating manual (Bulletin 57- 606).
Safety Function
The HART
®
version of the Eclipse
®
Enhanced Model 706
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- 606,
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., 3.6 mA or
21 mA).
The Enhanced Model 706 is certified for use in low
demand level measurement applications.
Application
The HART
®
version of the ECLIPSE Model 706
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 pres-
sure. It can be used in liquids, slurries, or solids with a
dielectric constant in the range 1.4 –100 to meet the
safety system requirements of IEC 61508 (Edition 2.0,
2010) and IEC 61511-1.
Benefits
• Level protection to SIL 3 as certified by exida
Certification per IEC 61508/IEC 61511-1.
• Probe designs to +850 °F (+454 °C), 6250 psig
(430 bar) and full vacuum.
• Cryogenic applications to -320 °F (-190 °C).
• Intrinsically safe, Explosion-proof and Non-Incendive
approvals.
• Quick connect/disconnect probe coupling.
