Rotary paddle level switch with EHEDG design - redefining point level measurement
With the innovative EHEDG design of the Rotonivo® RN3 and RN6 rotary paddle level sensors, we are setting new standards in point level measurement for bulk solids. This change represents an important advancement in point level measurement technology.
Upgrade for Rotonivo®
EHEDG certification sets new hygiene standards
Expanding the areas of application in sensitive industries
The improved design of the
rotary paddle switch expands its application range, enabling use in sensitive areas such as food production, pharmacy, and biotechnology. This adjustment helps to better meet the needs of these important industries.Depending on the application, the sensor can be used as a full, demand or empty detector in containers with bulk goods and fulfils the highest hygiene requirements with the EHEDG version.
Design improvements for increased hygiene
The design of the electromechanical detector has been extensively revised to comply with EHEDG guidelines. The contour of the process connection and the wall-flush weld-in socket has been adapted and now has a conical shape. This complies with the EHEDG specifications, which require an angle of at least 135° or a radius of at least 6 mm for all transitions for total cleanliness.
The stainless steel components and weld seams now have a surface quality greater than Ra 0.8 µm. In addition, all weld seams and all metals in contact with the product are polished by way of a technically complex process.




These adjustments were made with the aim of minimising dead spaces and making the cleaning of the installed sensors more efficient. For applications requiring high temperatures, the devices with an FKM shaft seal can now be used up to a temperature of 150°C.
PLUS security for your processes


EHEDG Certification: Understanding Its Significance
The EHEDG certification proves that the strictest hygiene regulations are adhered to. This is crucial for ensuring product quality and safety. The new EHEDG version of the Rotonivo® rotary paddle level switch opens up new possibilities for process optimisation in compliance with the highest hygiene standards.
Level measurement technology characterised by hygiene and innovation
The redesign of the Rotonivo® rotary paddle level switch to meet EHEDG standards demonstrates our commitment to meeting the specific hygiene and safety requirements of the food industry and other critical industries.
This illustrates our endeavour to meet the challenges of a wide variety of industries through technological advancements to increase their efficiency and safety.
