Rosemount 1408H radar level transmitter with IO-Link

Monday, 06 September, 2021 | Supplied by: Emerson Automation Solutions


To meet the need for highly accurate level measurement in hygienic applications, Emerson has developed the Rosemount 1408H Level Transmitter, which the company says is the world’s first non-contacting radar device designed specifically for the food and beverage industry.

Non-contacting radar is a suitable level measurement technology for applications that require stringent hygienic facilities and equipment. 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 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 in order to facilitate the removal of process residue during clean-in-place and sterilise-in-place processes.

The Rosemount 1408H uses 80 GHz frequency modulated continuous wave technology on a single electronic chip with embedded smart algorithms. This enables stronger radar beam focusing, so that internal tank obstructions such as agitators can be avoided and greater measurement accuracy achieved. Fast sweep technology also means collecting up to 40 times more information, increasing accuracy. The technology also enables measurements all the way to the top of the tank by eliminating radar dead zones.

The Rosemount 1408H is also said to be the first non-contacting radar transmitter with connectivity via the IO-Link communication protocol, making it easy to integrate with any automation system. The transmitter provides conventional analog 4–20 mA, switch outputs and digital high-speed communication.
