A radar level transmitter for hygienic applications
The Rosemount 1408H Non-Contacting Level Transmitter (photo) is said to be the world’s first IO-Link radar sensor for the food-and-beverage industry. Dedicated features include a hygienic compact design, fast sweep technology and exceptional radar-beam focusing. Non-contacting radar is an ideal level measurement technology for applications that require stringent hygienic facilities and equipment. It is virtually maintenance-free, which helps it to ensure long-term reliability, in sharp contrast to legacy technologies. It has a top-down installation that reduces the risk of product loss through leakage, and it is unaffected by process conditions, such as density, viscosity, temperature and pH. The compact and robust form of the Rosemount 1408H makes it a suitable solution for the small tanks and space-constrained skids commonly used in food and beverage production. The hygienic antenna is flush with the process connection that ensures the removal of process residue during clean-in-place and sterilize-in-place processes, and is insensitive to condensation and build-up. The hygienically approved, IP69-rated device has a stainless-steel housing with minimal crevices to withstand external washdowns and ensure cleanability. — Emerson, Gothenburg, Sweden
