Rosemount 3408 Non-Contacting Radar Level Transmitter Technical Data and Engineering Selection Guide
Rosemount 3408 Non-Contacting Radar Level Transmitter is supplied by SANTAN for new projects, installed-base replacement and complete model-code review. The verified information below supports preliminary engineering selection and quotation preparation.
Verified Product-Family Specifications
| Measurement principle | 80 GHz FMCW non-contacting radar |
|---|---|
| Media | Liquids, solids and slurry applications |
| Signal processing | Smart Echo Supervision for tracking the true product surface |
| Outputs | 4–20 mA/HART or WirelessHART models; optional Bluetooth configuration |
| Diagnostics | Health monitoring, historical data, remote verification and proof-test functions by model |
| Safety | SIL 2 certified configurations for eligible safety applications |
| Installation | Top-mounted; select antenna, process seal and nozzle arrangement for the vessel |
| Performance | Range and accuracy depend on antenna, medium, geometry and complete model code |
Published values describe the product family and are configuration dependent. Final range, accuracy, materials, pressure, temperature, approvals, communications and accessories must be checked against the selected Emerson/Rosemount model code and current documentation.
Best-Fit Application
Use the 3408 for broad liquid or solids level coverage where non-contact measurement, advanced diagnostics or wireless deployment adds value. Confirm dielectric properties, dust/foam, obstructions, nozzle geometry, safety function and communication architecture.
Quotation and Selection Data Required
| Application | Continuous level, interface, open-channel flow, alarm or overfill duty |
|---|---|
| Process | Liquid/solid properties, dielectric constant, density, viscosity, foam, dust and buildup |
| Geometry | Measuring range, tank/silo dimensions, nozzle, obstructions and mounting position |
| Design limits | Operating/design pressure and temperature; wetted-material requirements |
| Electrical | Power, wired/wireless output, update rate, enclosure and hazardous-area requirements |
| Compliance | SIL, hygienic, custody-transfer, drinking-water or other project approvals |
