No other level measure- HOW GUIDED WAVE RADAR WORKS ment technology has captured the attention of the process control industry the 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. 4 Eclipse Transmitters Eclipse has demonstrated an ability buildup, surface agitation, bubbling or to provide accurate and reliable meas- boiling, high fill/empty rates, low level urement at a performance level that and varying dielectric or specific gravity. surpasses many traditional technolo- Eclipse is at work worldwide in the gies.

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. pulldown 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 Model 705 GENERAL Signal Output SPECIFICATIONS 4–20 mA or 4–20 mA with HART (optional) 3.8 to 20.5 mA useable (meets NAMUR NE 43) FOUNDATION fieldbus™ or PROFIBUS PA™ Span Model 705: Resolution 6 inches to 75 feet (15 cm to 23 meters) Analog: 0.01 mA Display: 0.1 inch Loop Resistance General Purpose/Intrinsically Safe: 620 Ω @ 24 VDC (20.5 mA) Explosion Proof (with Intrinsically Safe electronics): 500 Ω @ 24 VDC (20.5 mA) Damping Adjustable 0–10 seconds Diagnostic Alarm Adjustable 3.6 mA, 22 mA, HOLD User Interface 3-button keypad with optional HART, FOUNDATION fieldbus™ or PROFIBUS PA™ communications Display 2-line × 8-character LCD Power at Terminals General Purpose/Intrinsically Safe: 11 to 28.6 VDC Explosion Proof: 11 to 28.6 VDC FOUNDATION fieldbus™ or PROFIBUS PA™: 9–30 VDC (17 mA current draw) Menu Language English, German, French or Spanish Housing Material Standard: Aluminum A356T6 (< .25% copper) Optional: 316 SS Net and Gross Weight 7 lbs.
