Emerson launches first native WirelessHART non-contacting radar level transmitter
The Rosemount 3408 Wireless Level Transmitter reliably measures the level of liquids and solids, even in remote locations where access is challenging. This makes it suitable for use in a broad range of industries, including energy, chemical, metals and mining, pulp and paper, construction and marine.
Oct. 30, 2025 (Emerson release) — Emerson, an industrial technology leader delivering advanced automation solutions, has launched the world’s first native WirelessHART® non-contacting radar level transmitter.
The Rosemount™ 3408 Wireless Level Transmitter – Non-Contacting Radar reduces the complexity, time and costs associated with installing cabling in automated measurement points. By eliminating measurement blind spots and the need for manual readings, the transmitter enhances plant safety, boosts operational efficiency, and enables more reliable, continuous level monitoring in industrial environments.
Based on 80 gigahertz frequency modulated continuous wave (FMCW) technology, the Rosemount 3408 Wireless reliably measures the level of liquids and solids, even in remote locations where access is challenging. This makes it suitable for use in a broad range of industries, including energy, chemical, metals and mining, pulp and paper, construction and marine.
“The Rosemount 3408 Wireless is a game-changing level transmitter, with reliable WirelessHART connectivity making it the ideal solution for efficient, hassle-free monitoring of remote assets,” said Rana Zangeneh, product manager for Emerson’s measurement solutions business. “The valuable insights gained through the delivery of secure, reliable, real-time process data and advanced diagnostics enable better-informed decisions, ultimately leading to enhanced operational efficiency and safety, minimized downtime, improved maintenance strategies, and increased profitability.”
In alignment with Emerson’s Boundless AutomationSM vision for seamless data mobility, real-time measurement and diagnostic data is transmitted via the WirelessHART communication protocol. The 3408 can also be easily integrated into any host monitoring and control system compliant with the HART® protocol and the Field Device Integration® (FDI) standard. This makes it easy for operations and maintenance teams to obtain clear visibility of data that may previously have been siloed, resulting in improved operational performance and inventory management.
The new transmitter features a diagnostics suite, providing actionable insights into device and process health, leading to long-term measurement reliability, reduced lifecycle costs, and enhanced operational efficiency and safety. Emerson’s proprietary diagnostic software, Smart Meter Verification, provides in-situ performance validation without interrupting the process, while Signal Quality Metrics delivers continuous, real-time assessment of radar signal quality and early alerts of abnormal conditions. In addition, on-board data historian functionality enhances operational insight, streamlines troubleshooting and supports proactive maintenance by continuously recording and storing key measurement and diagnostic data.
The 3408 has a modular electronics cassette that can be quickly removed or replaced without disturbing the field wiring or process seal. The availability of different seals and antenna types increases the range of applications for which the transmitter is suitable. With two power modules, organizations can adjust the update rate to suit their needs and obtain extended battery life with a slower update rate.
