Pulsar® Model R96 Pulse Burst Radar Level Transmitter D E S C R I P T I O N The Pulsar® R96 Radar transmitter is the latest generation of Magnetrol® 24 VDC, loop-powered, noncontact radar transmitters. Enhanced performance and innovative diagnostics bring simplicity to an often complicated technology. This latest entry into the radar level measurement field is designed to provide unparalleled performance and ease of use. PULSAR non-contact radar is the perfect compliment to the MAGNETROL Eclipse® Model 706 Guided Wave Radar transmitter. Together, these transmitters offer the ultimate solution to the vast majority of process level applications. F E A T U R E S • Multivariable two-wire, 24 VDC loop-powered transmitter for level or volume • Performance not process dependent (changing specific gravity and dielectric have no effect) The PULSAR Radar transmitter is based on pulse burst radar technology combined with equivalent time sampling circuitry. Short bursts of 6 GHz microwave energy are emitted and subsequently reflected from the liquid level surface. Distance is calculated by the equation D = Transit time (round-trip)/2. Liquid level is then calculated by applying the tank height value. • 6 GHz operating frequency offers superior performance in the tougher applications with turbulence, foam, and heavy vapors • Echo Rejection setup is simple, intuitive and effective • Antenna designs to +400°F (+200°C), -14.7 to 750 psig (-1.0 to 51.7 bar) • Range up to 130 feet (40 meters) • Quick connect/disconnect antenna coupling allows vessel to remain sealed A P P L I C A T I O N S MEDIA: Liquids and slurries; hydrocarbons to waterbased media (dielectric 1.7–100) VESSELS: Most metal and concrete process or storage vessels up to rated temperature and pressure. Pits and sumps as well as glass-lined tanks. CONDITIONS: Virtually all level measurement and control applications including process conditions exhibiting varying specific gravity and dielectric, visible vapors, high fill/empty rates, turbulence, low to moderate foam and buildup. • Extremely low output at antenna: < .01 mW (avg), < 2 mW (max); hundreds of times less than a cell phone • 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 • Available for use in SIL 2 Loops (92.7% SFF, with full FMEDA report available • PACTware™ PC Program and enhanced DTMs for advanced configuration and troubleshooting • Available with HART® or F

PULSAR R96 is a top-mounted, downward-looking pulse burst radar operating at 6 GHz. Unlike true pulse devices (e.g. ECLIPSE Guided Wave Radar) which transmit a single, sharp (fast rise-time) waveform of wide-band energy (Figure 1), PULSAR emits short bursts of 6 GHz energy (Figure 2) and measures the transit time of the signal reflected off the liquid surface. Distance is calculated utilizing the equation Distance equals the Speed of light multiplied by the transit time divided by two (Distance = C × Transit Time/2), then developing the level value by factoring in tank height and other configuration...

Radar applications are characterized by three basic conditions: • Dielectric (process medium) Sensor Reference Point • Distance (measuring range) • Disturbances (turbulence, foam, false targets, multiple reflections and rate of change) Safety Zone Sensor Level Distance Measurement Region Tank Height The PULSAR R96 Radar transmitter is offered with three antenna configurations: Level Trim • TFE Dielectric Rod Level = Tank Height – Distance Bottom Blocking Distance Maximum measuring range (distance) is measured from the sensor reference point (bottom of NPT thread, top of BSP thread, or face of...

The PULSAR Model R96 Radar transmitter can be mounted on a vessel using a variety of process connections. Generally either a threaded or flanged connection is used. L O C A T I O N Ideally, the Radar transmitter should be mounted 1⁄2 radius from center of the tank providing an unobstructed signal path to the liquid surface where it should illuminate (with microwave energy) the largest possible surface area. Do not install in center of tank top or within 18 inches (45 cm) of tank wall. Tank walls may produce reflections that must be minimized during field configuration (Antenna Orientation). Refer...

Improper installation in a nozzle creates “ringing” (undesired signals) which will adversely affect measurement. The antenna should always be mounted so the active section of the antenna is a minimum of 0.5" (12 mm) below the nozzle. Be sure to include any nozzle dimension inside the vessel. Refer to Figure 10. Antenna extensions are offered to allow the PULSAR Model R96 transmitter to work reliably in nozzles with “L” dimensions of 1" (25 mm), 4" (100 mm), 8" (200 mm) or 12" (300 mm). Standard antennas are shown below for reference. Dielectric Rod Antenna Coupling Inactive Area Horn Antenna...

The PULSAR Model R96 can be mounted in a standpipe or stillwell but certain items must be considered: • Metal stillwells only: Sizes 4–8 inches (100–200 mm). Index Mark • Diameter must be consistent throughout length; no reducers. • Use only horn antennas sized to pipe ID; 4–6" (100–150mm); 8" pipe can use a 6" horn. • Stillwell length must cover complete range of measurement (i.e., liquid must be in stillwell). • Welds should be smooth. • Vents: holes <0.5" diameter, slots <0.5" width. • If an isolation valve is used, it must be a full port ball valve with an I.D. equal to the pipe diameter....
