clipse transmitters utilize Guided Wave Radar

(GWR) technology for unsurpassed accuracy and

reliability in monitoring liquid levels. Though GWR

technology was first employed for the detection of

underground cable breaks as early as the 1930s,

Magnetrol pioneered its use for liquid level measure-

ment with the introduction of the Eclipse 705 transmitter

in 1998. No other level measurement technology has

captured the attention of the process

control industry the way Eclipse has in

the short time since its introduction.

PPrriinncciippllee ooff OOppeerraattiioonn

Guided Wave Radar functions accord-

ing to the principles of Time Domain

Reflectometry (TDR) and Equivalent Time

Sampling (ETS). As shown at left, a gen-

erated pulse of electromagnetic energy

travels down the probe. Upon reaching

the liquid surface the pulse is reflected.

ETS 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 set-up and configura-

tion. A compact instrument that is easy to

handle and install, Eclipse’s housing

makes measurement data easy to read.

An Introduction To Eclipse Guided Wave Radar

Eclipse transmittersgenerate pulses ofelectromagneticenergy that aretransmitted downthe probe, or wave-guide.

When they reach aliquid surface thathas a higher dielec-tric than the air orvapor in which theytravel, the pulsesare reflected.

The pulses’ transittime to and fromthe surface is meas-ured, converted todistance, then dis-played on the LCDas a level reading.

ment at a performance level that sur-

passes many traditional technologies.

This is due to the efficiency of Guided

Wave Radar technology and to

Magnetrol’s broad range of sensing

probes designed to meet the special

demands of temperature, pressure,

viscosity, liquid interface, vessel depth

and other variables discussed ahead.

Eclipse accurately measures liquids

and slurries with a dielectric range of

1.4 to 100, from hydrocarbons to

water-based media. The transmitters

perform in all conventional process

and storage vessels, bridles and

bypass chambers whose temperatures

and pressures are rated to the capabil-

ities of the particular probe used.

There is a probe for virtually every

application, from routine water stor-

age to vessels exhibiting corrosive

vapors, foam, steam, coating and

build-up, surface agitation, bubbling

or boiling, high fill/empty rates, low level and varying

dielectric or specific gravity. In addition, the new

Model 707 Eclipse transmitter and its dedi-

cated 7XT probe have been engineered

exclusively for interface level measure-

ment.

Eclipse is at work worldwide in the

most demanding applications, including

those in petroleum refining, electric power

generation, chemical manufacturing, water

and wastewater, pulp and paper, food and

beverage, and pharmaceutical processing.

Eclipse also serves as the ideal retrofit

transmitter made possible by Magnetrol’s

wide range of adaptation hardware for

easy and affordable replacement of anti-

quated level measurement technology.

Eclipse transmitters have been engi-

neered to provide users with the total

range of measurement solutions in Guided

Wave Radar. With probe-specific transmit-

ters and an extensive line of dedicated

coaxial, single rod and twin rod probes,

Eclipse has emerged as the premier measurement

instrument for today’s liquid level challenges.

Process ConnectedBecause the Guided

Wave Radar signal istransmitted via thewaveguide directly intothe process media, it isnot distorted by tankatmospheres, processconditions, tank obstruc-tions or false echoes.

HHiigghh PPeerrffoorrmmaannccee,, LLooww PPoowweerr Eclipse transmitter Models 705, 707 and 708 are

advanced two-wire, 24 VDC, loop-powered transmitters.

A microprocessor controls the measurement engines,

powers the liquid crystal display, enables keypad opera-

tion, controls the optional HART® communications and

provides a 4-20 mA output for level.

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 sig-

nificant amounts of media build-up on a single rod probe

will not affect accurate detection of liquid level.

Eclipse Models 705 and 708 utilize many special pur-

pose probes while the new Model 707 and its companion

7XT probe is specialized for interface measurement only.

Eclipse probes include high-temperature (to +750° F /

+400° C), high-pressure (to 5000 psig / 345 bar) and

ultra-low dielectric (≥ 1.4).

DDuuaall--CCoommppaarrttmmeenntt DDeessiiggnnEclipse’s innovative dual-compartment enclosures ori-

ent separate wiring and electronics compartments on the

same plane and angle for convenient wiring, configura-

tion 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 set-up 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 sim-

ply 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.
