Transducer Shown in Kynar; available in polypropylene. Transducer Board Piezoelectric Crystal Assembly 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. Smart Signal Processing Overcomes Measurement Difficulties 355 Ultrasonic Transmitter 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. • • • • • • Chemical storage tanks Vessels with highly viscous media Paint, ink and solvent tanks Food and beverage vessels Batch and day tanks Open channel flow weirs and flumes R82 Radar Transmitter 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 fullyencapsulated 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 Fill pipe Ladder and fill pipe obstacles Agitator blade shaft Visible vapors Turbulent process Aerated process; in-tank air movement R82 RADAR TRANSMITTER Model R82 with a thermoplastic housing and a polypropylene antenna; and a Model R82 with a cast aluminum housing and a Tefzel® antenna Housing Covers Model R82 is a loop-powered, TOP LEFT: Cast aluminum with a tempered glass window.
