Pulses
Generated
Eclipse transmitters
generate pulses of
electromagnetic
energy that are
transmitted down
the probe, or waveguide.
Pulses
Reflected
When they reach a
liquid surface that
has a higher dielectric than the air or
vapor in which they
travel, the pulses
are reflected.
Time Converted
to Distance
The pulses’ transit
time to and from
the surface is measured, converted to
distance, then displayed on the LCD
as a level reading.
way Eclipse has.
Principle of Operation
Guided Wave Radar functions according to the principle of Time Domain
Reflectometry (TDR). As shown at left, a
generated pulse of electromagnetic energy
travels down the probe. Upon reaching
the liquid surface the pulse is reflected.
Sophisticated circuitry captures these signals in real time (nanoseconds) and
reconstructs them in equivalent time
(milliseconds) to make level measurement
a practical reality.
Unlike conventional radar, which
launches its signal into free air, Eclipse
launches its signal within the sealed path
of its probe (wave guide) which is in
direct contact with the process media.
This direct contact makes the signal less
vulnerable to distortion brought on by
process conditions that might thwart
through-air technologies.
Eclipse transmitters have also been
designed for easy setup and configuration. A compact instrument that is easy to
handle and install, Eclipse’s innovative
housing makes measurement data easy
to read.

High Performance, Low Power
Dual-Compartment Design
Eclipse transmitter Model 705 is an advanced two-wire,
24 VDC, loop-powered transmitter. A microprocessor controls the measurement engine, and provides an analog
4–20 mA signal with HART Communication or a digital
FOUNDATION fieldbus™ signal.
As a Guided Wave Radar instrument, Eclipse’s
measurement performance is not process-dependent,
so changing specific gravity and dielectric have little or
no effect on measurement accuracy. The measurement
engine of Eclipse is optimized under software control to
provide continuous and reliable level detection. Even significant amounts of media buildup on a single rod probe
will not affect accurate detection of liquid level.
Eclipse Models 705 utilizes many special purpose
probes. Eclipse probes include high-temperature (to
+750° F / +400° C), high-pressure (to 5000 psig /
345 bar) and ultra-low dielectric (≥ 1.4), and bulk solids
with 3000 lb. pull-down capability.
Eclipse’s innovative dual-compartment enclosures orient separate wiring and electronics compartments on the
same plane and angle for convenient wiring, configuration and data display. The wiring compartment at the top
of the transmitter isolates the power/signal conductors
from the electronics compartment beneath it by way of
an environmentally sealed feed-through. The electronics
are surge and transient protected and are angled at 45°
for convenient setup and data display. All Eclipse models
have received Intrinsically Safe, Explosion Proof, and
Non-Incendive approvals.
A quick-disconnect probe coupling eases installation
and servicing needs on all Eclipse models. Probes may
be installed without concern for their orientation to the
transmitter head. To orient the transmitter, the user simply selects the desired position, tightens the coupling,
then completes the wire terminations.
As an added convenience on all Eclipse models,
a level change is not required for configuration and
no field calibration is necessary. 6
