O-Ring Aluminum Housing: Viton® Lexan® Housing: Buna-N Echotel® Model 355is a two-wire, loop-powered, non-contact ultrasonic transmitter that performs liquid level, volume, and open channel flow measurement. A powerful 60 kHz ultrasonic transducer and advanced digital signal processing is featured to reliably measure out to a 20 foot (6 meter) maximum range. The Model 355 provides unsur- passed ease of configuration with either the menu-driven 4-pushbut- ton, 2-line× 16-character display, HART ® digital communications, or PACTware ™ . The latter enables a complete configuration via the local user interface, or remotely with the added capability of capturing echo waveforms, and viewing trend data, diagnostic conditions and all trans- mitter configuration parameters. Operating Principle Measurement is obtained by emitting an ultrasonic pulse from the transducer and measuring the time required for the echo to reflect from the liquid surface and return to the transducer.

Piezoelectric Crystal Assembly Transducer Board TransducerShown in Kynar; available in polypropylene.
The intelligent electronics of the Model 355 Transmitter analyze the ultrasonic echo profile, apply temperature compensation, reject echoes from false targets, and then processes the true echo from the liquid surface. This results in an extremely reliable measurement even when application difficulties exist like turbulence or false echoes generated by agitator blades, fill pipes or other internal tank fittings. The 60 kHz ultrasonic transducer is offered in polypropylene or Kynar for superior performance in harsh environments. These powerful transducers feature a 10° conical beam and 10" (255 mm) blocking distance to maximize measurement capabilities in a wide variety of applications.

355 Ultrasonic Transmitter
Overcomes Measurement Difficulties The sophisticated circuitry of the R82 transmits, receives and processes 1.8 million pulses per second to ensure reliable measurement. The R82 measures effectively even when atmospheres above the liquid are saturated with vapor. Pulse Burst technology and advanced signal processing manage common disturbances such as false echoes caused by obstructions, multi-path reflections from tank sidewalls or turbulence caused by agitators, aggressive chemicals, or aerators. The R82 launcher orientation and echo-rejection profiling are simplified for easy use. The microwave beam is rotatable for optimized operation. The fully- encapsulated horn antenna offers high performance and is chemically resistant to nearly all standard process media. Applications include:
- Liquids, slurries and viscous media
- General chemical storage
- Day, batch and feed tanks
- Food and beverage vessels
- Water/Wastewater tanks and sumps R82 Radar Transmitter Agitator blade shaft Fill pipe Turbulent process Ladder and fill pipe obstacles Visible vapors Aerated process; in-tank air movement

Contains field wiring compartment and electronics. Model R82is a loop-powered,
26 GHz, non-contact radar transmitter
that performs liquid level and volume measurements in enclosed vessels. The R82 offers high-performance at an economical price point to reliably measure out to a 40 foot (12 meter) maximum range. The Model R82 provides unsurpassed ease of configuration with either the menu-driven 4-pushbutton, 2-line× 16-character display, HART digital communications, or PACTware. This allows complete configuration via the local user interface, or remotely with the added capability of capturing echo waveforms, and viewing trend data, diagnostic conditions and all transmitter configuration parameters.

Available in two lengths. Antennahorn is encapsulated within polypropylene or Tefzel. Operating PrincipleThe R82 is based on pulse burst radar technology together with equivalent time sampling circuitry. Short bursts of
26 GHz microwave energy
are emitted and subsequently reflected from the liquid level surface. ) ) ) ) R82 R A D A R T R A N S M I T T E R O-Ring Aluminum Housing: Viton® Lexan® Housing: Buna-N
