Product Description

Rosemount™ 5900S Radar Level Gauge / Transmitter

The Rosemount™ 5900S Radar Level Gauge/Transmitter is a high-performance solution engineered to deliver accurate, reliable, and non-contact level measurement for liquids and solids in demanding industrial environments. Leveraging advanced Frequency Modulated Continuous Wave (FMCW) radar technology, this transmitter ensures exceptional precision with ±1 mm accuracy for liquids and ±5 mm for solids, making it ideal for applications in oil and gas, chemical processing, water/wastewater treatment, and food & beverage industries. Its robust design, global certifications, and seamless integration with digital ecosystems position it as a trusted choice for mission-critical operations.

The 5900S operates with a 24–26 GHz K-band frequency (or optional 80 GHz for enhanced resolution), enabling stable measurements in challenging conditions such as turbulence, foam, and vapor. The horn or parabolic antenna (SS 316/PTFE-coated) provides narrow beam angles (4°–12°) to minimize interference and ensure signal integrity even in large tanks up to 40 meters (131 ft) deep. Its 4–20 mA + HART® 7 output supports bidirectional communication for remote configuration, diagnostics, and calibration via tools like Emerson AMS Suite or DeltaV™ systems. Optional Foundation Fieldbus or Modbus protocols further enhance flexibility for process automation integration.

Built for harsh environments, the 5900S features an IP66/IP67-rated enclosure (NEMA 4X compliant) and operates within -196°C to +200°C (-321°F to 392°F) process temperatures and -40°C to +70°C (-40°F to 158°F) ambient ranges. It meets global hazardous area certifications, including ATEX, IECEx, FM, and SIL 2, ensuring safe deployment in explosive atmospheres (Zone 1/2) and sour service environments (NACE MR0175). The transmitter's -1 to 40 bar (g) pressure rating accommodates diverse tank and vessel requirements, while materials like SS 316/316L, PTFE, and PEEK resist corrosion in aggressive media.

Advanced diagnostics enhance operational efficiency by providing real-time echo curve visualization, signal quality alerts, and self-checks during startup. Features like stilling well compatibility and hygienic clamp mounting ensure adaptability to agitated tanks, sanitary processes, or retrofit projects.
