Vibration level sensor meets rigorous standards in tea production

Precise level measurement in dusty environments: UWT’s vibrating level switch Mononivo® ensures the highest quality in the food industry
A renowned producer of yerba mate in Argentina was faced with the challenge of reliably monitoring the limit levels in a new production plant. The product itself presented particular challenges: A high-dust suspension with a low density of 400 g/l - and the need for specific certification for the food sector. Given the importance of this monitoring of over 100 measuring points, the customer focused on the durability and reliability of the sensors to be used.

The plant operator needed a solution for precise control of low and very low fill levels that could meet the demanding conditions of the dusty and lightweight product. Additionally, the sensors had to comply with strict food safety standards and offer high reliability across a multitude of measuring points.

Precise measurement at minimum fill levels

For these specific requirements, UWT GmbH selected the Mononivo® - MN 4020 vibration switch. This sensor impresses with its high sensitivity, which can be adjusted in four stages from 20 g/l, thus enabling precise measurement even at very low densities. For the 4 metre high single chamber silos, the vibrating rod was installed at the side. This enabled customised fulfilment of specific customer requirements.

The vibration sensor made of high-quality stainless steel is only 155 mm long and provides fast and reliable switching signals. Due to its high sensitivity, the point level probe is suitable for long-term overfill protection as well as for open circuit protection in very light solids or powders.

The Mononivo® - MN 4020 has proven to be an excellent choice for the Argentinian yerba mate producer as it delivers precise and reliable measurement results, which are essential for efficient production. With this sensor, UWT not only ensures maintenance-free use, but also a long-term partnership, backed by a comprehensive six-year warranty. The successful use of this sensor has enabled the customer to increase the efficiency and precision of its production processes and ensure product quality.

This application once again demonstrates how UWT, with its innovative technology and strong focus on customer needs, provides customised solutions that meet the most stringent requirements.
