3408 Non-Contacting Level Transmitter

The Rosemount™ 3408 Non-Contacting Radar Level Transmitter delivers reliable, continuous level measurement for grain, corn, DDGS, biomass, and other bulk solids storage applications. Featuring an advanced solids algorithm and Smart Echo Supervision™ technology, the 3408 provides accurate inventory visibility in dusty silos and bins where traditional measurement methods often struggle.

Optimized for grain and corn storage: Advanced solids measurement algorithms strengthen weak radar signals, reduce noise, and provide stable level readings in dusty, low-dielectric materials such as corn, grain, DDGS, and biomass. Ideal for silos and bins up to 98 ft (30 m). 

Reliable performance in challenging environments: Smart Echo Supervision™ technology and the process seal antenna help maintain measurement reliability despite dust, buildup, condensation, and internal silo obstructions. 

Improved inventory visibility and safer operations: Built-in diagnostics, Signal Quality Metrics, and historical data provide proactive maintenance insights while reducing the need for manual silo climbs and inventory checks. SIL 2 certification for solids applications helps enhance safety and protect personnel, assets, and production continuity.
