LEVEL MEASUREMENT SOLUTIONS The Pulsar® Model R80 radar transmitter is the latest generation of Magnetrol® 24 VDC, loop-powered, non-contact radar transmitters. Utilizing Frequency Modulated Continuous Wave (FMCW) radar technology, this transmitter offers enhanced performance, proactive diagnostics, and various configuration wizards to bring simplicity to an often complex technology. This latest entry into the radar level measurement field is designed to provide unparalleled performance and ease of use. The 80 GHz Pulsar Model R80 is the perfect complement to our 6 GHz Pulsar Model R96 and 26 GHz Model R86 radar transmitters. Together, this transmitter family, along with the acclaimed Model 706 GWR transmitter, offers the ultimate solution set for those difficult industrial process level applications. The Pulsar Model R80 radar transmitter is based on FMCW radar technology. Transmitting a continuous signal with a constantly changing frequency down toward the process medium, the difference in the frequencies detected between the transmitted signal and return echoes is a function of the distance. Level is then calculated based on transmitter configuration. MEDIA: Liquids, slurries and solids; dry bulk solids to water- based media (dielectric 1.4-100) VESSELS: Most process or storage vessels up to rated temperature and pressure. Silos, pits, and sumps as well as glass-lined tanks. CONDITIONS: Virtually all level measurement and control applications including those exhibiting varying dielectric, visible vapors, high fill/empty rates, turbulence, low to moderate foam and buildup. • Multivariable two-wire, 24 VDC loop-powered transmitter for level, volume, or flow • Performance not process dependent (changing specific gravity and dielectric have no effect) • 80 GHz operating frequency offers superior performance, smaller antennas, better accuracy and enhanced resolution • Available with hygienic (15 Ra) surface finish and Tri-Clamp process connections • 4-button keypad and graphic LCD display allow for convenient viewing of configuration parameters and echo curve • Proactive diagnostics advise not only what is wrong, but also offer troubleshooting tips • SIL 2 suitable (92.3% SFF, with full FMEDA report available) • PACTware™ PC program and enhanced DTMs for advanced configuration and troubleshooting • Available with HART® digital outpu

TECHNOLOGY FREQUENCY MODULATED CONTINUOUS WAVE (FMCW) RADAR The detected difference in frequencies between the transmitted signal and return echo is a function of the distance. See Figure 1 at right. Level is then calculated by factoring in tank height and other configuration information. FMCW captures its process variable information in the frequency domain, which supports more accurate signal conversion. The main advantage of FMCW is that it The Pulsar R80 is a top-mounted, downward-facing FMCW radar transmitter operating at 80 GHz. Unlike previous Pulsar transmitters that emit short bursts...

Figure 3 shows the maximum measuring range of each antenna size based on the dielectric and turbulence of the application. (Obstructions, noise and media buildup can affect reliable measurement.) R80 Maximum Recommended Measuring Range in meters (feet) Although it is theoretically possible to measure a liquid level on the antenna, liquid should not be allowed closer than 50 mm (2 inches) from the bottom of the antenna. The Pulsar Model R80 Radar transmitter can be mounted on a vessel using a variety of process connections. Generally either a threaded or flanged connection is used. Ideally, the...

MOUNTING NOZZELS Improper installation in a nozzle can create “ringing” (undesired signals) which can adversely affect level measurement. Be sure to include any nozzle dimension that may extend down inside the vessel. Refer to Figure 8. (As nozzle influence is application dependent, please consult factory in cases where suggestions cannot be met.) The Pulsar Model R80 can be mounted in a standpipe or stillwell but certain items must be considered: • Metal stillwells only • Diameter must be consistent throughout length; no reducers or gaps. • Use horn antennas sized to pipe ID; 20-100mm (3/4"-4");...
