Eclipse
talks Fieldbus Foundation
Posted: 4 March 2004
The Eclipse 705 series adds Fieldbus Foundation communication to
the existing Hart / AMS protocols. The loop powered Eclipse Guided
Wave radar distinguished itself by providing the most complete GWR
offering in the world, serving applications such as HTHP (-150°C
up to +400°C / full vacuum to 345 bar), interface, saturated
steam and viscosity up to 10.00 cP.
All of the benefits of Fieldbus are included in the 705 series:
Installation
The H1 Fieldbus allows many devices to connect to a single wire
pair, and distribution of control into the field devices. This results
in less wire and reduction of the amount of I/O and control equipment
needed, including card files, cabinets and power supplies.
Design
Interoperability, defined as the "ability to operate multiple
devices in the same system, independent of manufacturer, without
loss of functionality" allows for time savings in the design
stage and added flexibility after installation.
Functionality
Full digital communication allows multiple variables to be brought
back from each device for control, trending, reporting.
Maintenance
The self-diagnostics residing in the smart field devices minimizes
the need to send maintenance personnel to the field.
Guided Wave Radars are known for delivering a high quality &
stable measurement even under the most harsh process conditions.
Since its signal travels over a GWR probe, almost no amplitude is
lost, allowing the unit to measure in conditions suffering from
heavy turbulence, foam, varying temp and pressure, changing density,
pH and dielectrics. Eclipse has gained worldwide confidence as a
superior but lower cost replacement of displacer and DP transmitters.
Existing by-pass cages don't need any modification to accept the
Eclipse electronics and GWR probe.
The Eclipse 705 with Fieldbus Foundation is offered with all existing
coaxial and twin rod probes; its electronics are in compliance with
all safety ratings including ATEX Fisco EEx ia and ATEX EEx d and
can be used in SIL safety loops.
