Level Measurement in Ore Warehouses for Talc Production
Accurately measure talc ore levels in real-time despite challenging, dusty conditions in storage silos.
Reliable Level Monitoring and Control with Radar and Switch Technology
Talc ore is delivered from open pit mines to a warehouse at the start of the milling process. Talc ore is stored in piles in warehouses where the warehouse size or the irregular surface of piles of material make accurate, real-time measurement challenging. Operators need to accurately measure the inventory level on a daily basis to ensure material is available for production. Installing reliable level switches helps control the emptying and filling cycles.

Product Solutions
The Rosemount™ 5408 Non-Contacting Radar Level Transmitter uses enhanced technology and Human Centered Design to deliver accurate, reliable measurements on both liquid and solid materials. Using two-wire FMCW and Smart Echo Supervision technologies, the Rosemount 5408 deploys a continuous echo to maximize radar signal strength and produce a more robust and reliable measurement. Delivering ease-of-use at every touch point, the Rosemount 5408 uses an intuitive software interface to guide the operator through installation, commissioning, proof-testing and maintenance. Powerful onboard diagnostics suite proactively monitors transmitter health and alerts if there is an issue. Safety certified to IEC 61508 for SIL 2 applications, the Rosemount 5408:SIS reduces cost of risk, increases efficiency and protects people and the environment.
- With Smart Echo Supervision™ technology, Rosemount Non-Contacting Radars automatically track all echoes, including those from obstructions in the vessel, and distinguish them from the real product surface echo. This ensures the true product level is reliably and accurately reported.
