Product Description

Emerson Rosemount 3301 Guided Wave Radar Level Interface Transmitter

The Emerson Rosemount 3301 Guided Wave Radar (GWR) Level Interface Transmitter is a high-precision, industrial-grade solution designed for reliable liquid, solid, and interface level measurement in demanding environments. Leveraging advanced guided wave radar technology, this transmitter delivers unmatched accuracy and durability across critical applications in oil and gas, chemical processing, power generation, water treatment, and food and beverage industries. Its integration of HART® 7 communication ensures seamless compatibility with modern process control systems while maintaining backward support for legacy infrastructure.

Core Technical Performance The Rosemount 3301 offers ±1 mm (±0.04 in) or ±0.1% of span accuracy, whichever is greater, with a measurement range of up to 20 meters (66 ft) for liquids and 6 meters (20 ft) for solids. It provides a 4–20 mA analog output paired with HART® 7 digital communication, enabling remote configuration, diagnostics, and calibration via tools like the Emerson Field Communicator. Powered by 10.5–42 V DC loop power, the transmitter operates reliably in extreme ambient temperatures from -40°C to +85°C (-40°F to +185°F), with response times under 100 milliseconds to ensure real-time process monitoring and control.

Innovative Design and Durability The 3301 features 316L Stainless Steel, Hastelloy C-276, or Tantalum probe materials, ensuring compatibility with corrosive, abrasive, or high-temperature media. Available with single, twin, or coaxial probes, it adapts to diverse process conditions, including foaming liquids, emulsions, and bulk solids. The IP66/IP67-rated aluminum or stainless steel enclosure protects against dust, moisture, and mechanical impacts, while its sensors withstand vibration (2g RMS) and shock (50g), ensuring reliability in harsh environments such as offshore platforms, refineries, and chemical plants.

Advanced Communication and Diagnostics Equipped with HART® 7, the 3301 enables bidirectional communication for real-time monitoring of sensor health, process anomalies, and predictive maintenance alerts. This protocol supports integration with PLCs, DCS, and SCADA systems, reducing unplanned downtime. For safety-critical applications.
