Food & Beverage World’s First Non-Contacting Radar Level Transmitter

Editor: Ahlam Rais

To meet the need for highly accurate and reliable level measurement in hygienic applications, Emerson has developed the Rosemount 1408H Level Transmitter, the world’s first non-contacting radar device designed specifically for the food and beverage (F&B) industry.

Dedicated features of the transmitter include a hygienic compact design, fast sweep technology, exceptional radar beam focusing and IO-Link communications, helping manufacturers to optimise the efficiency of their operations, reduce product losses and ensure food safety, states the company.

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 transmitter makes it a suitable solution for the small tanks and space-constrained skids commonly used in food and beverage production, adds the firm. The hygienic antenna is flush with the process connection that ensures the removal of process residue during clean-in-place and sterilise-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.

It is the first level transmitter to use 80 GHz frequency modulated continuous wave technology on a single electronic chip with embedded smart algorithms. This enables exceptional radar beam focusing, so that internal tank obstructions such as agitators can be avoided, and greater measurement accuracy achieved, mentions the company.

Fast sweep technology makes the transmitter the quickest level measurement technology on the market, collecting up to 40 times more information than legacy transmitters. This increases measurement accuracy, enabling manufacturers to reduce the amount of product lost through wastage, maximise production capability, and reduce production variations, leading to increased product quality and batch consistency. The technology also enables measurements all the way to the top of the tank, with this elimination of radar dead-zones enabling users to maximise vessel utilisation, opines the firm.
