Rotary paddle Rotonivo® the reliable solution for level control

Simple and reliable measurement technology by UWT

A level limit sensor has to cope with low bulk density, bridging, caking, abrasiveness, corrosion, leverage forces, high and low process temperatures, electrostatic charging and so on. Rotating level limit switches of UWT have been designed to meet these challenges of different industry sectors and cover various changing approaches, also within extraordinary applications. The rotating paddle switch can be used as full, demand or empty detectors in silos or containers.
The trusted, multifunctional and maintenance free unit for level monitoring of bulk goods is versatile and has a modular design. With its simple electromechanical measuring principle it can also be adapted for extreme process conditions. A motor driven shaft causes the vane to rotate. Once the material level reaches the vane, thereby preventing further rotation, this creates a torque, which is converted via a switch to an electric signal. When the vane is free again of the material, the output signal is reset and the motor driven shaft rotates again.

The Rotonivo® provides very precise level limit detection as the sensor is unaffected by dust as well as the build-up of adhesion. The Rotonivo® 3000 models as high temperature version handle process temperatures up to +1100°C. Depending on the given conditions the units are equipped with the necessary sealing (Viton, Teflon, Ceramics). The simple and reliable measuring device is easy and fast installed and needs no further maintenance.
The PNP electronics for the Rotonivo® RN 3000 and RN 4000 ranges uses 3-wire electronics technology with a non-contact output, open collector, PNP. These electronics can be connected to any standard PLC with 24V DC power supply and PNP input card.
Further the sensor has a mechanically stable shaft bearing design with ball-bearing and a robust aluminum die-cast housing.

With the whole Rotonivo® portfolio being internationally certified with amongst others ATEX, FM and new Inmetro and TR-Cu-Ex it is conform to regulations for use in hazardous areas all around the world. The Rotonivo® 6000 series is also certified to SIL 2 (safety integrity level 2), particular for systems with hazard-causing processes, such as in chemical plants where the consideration of functional safety has become indispensable.

Trade Show ACHEMA 2021
ACHEMA is the world forum for chemical engineering, process engineering and biotechnology. Every three years the world’s leading show for the process industry attracts around 3,800 exhibitors from over 50 different countries to present new products, processes and services to 150,000 professionals from all over the world. The spectrum ranges from laboratory equipment, pumps and analytical devices to packaging machinery, boilers and stirrers through to safety technology, materials and software, thus covering the entire needs of the chemical, pharmaceutical and food production industries. The accompanying congress, featuring 800 scientific lectures and numerous guest and partner events, complements the wide range of themes of the exhibition. Focal topics are identified anew for every ACHEMA and feature topics that are currently trending in industry. In 2021, they are - The digital lab: In the lab data from every stage of research and production converge. Modularly designed and fully connected, the digital lab is a data mine for process design and quality control. - Product and process security: The interfaces between the real and the virtual world demand special attention in times of industry 4.0 and Internet of Things. - Modular and connected production: A fully connected value chains makes faster product cycles possible as well as small batches of specialized products. Based on the proven ACHEMA concept with its unique range of topics and the established interplay of exhibition and congress, the organizers at Dechema are currently working on new formats that will offer even more opportunities for discussion and networking. These include matchmaking tools as well as new interactive event formats. They are intended to stimulate discussion and provide additional impulses. The hall layout has also been slightly adapted to make optimum use of the structural changes on the exhibition grounds and to integrate the brand new Hall 12, located right in the center. Thus ACHEMA, which celebrates its centenary in 2020, offers the opportunity to truly experience the latest solutions and products for the process industry and to make global contacts.
