Contents measurement in PVC-granulate

The Challenge

Our customer is the greatest producer of building elements based on PVC in Russia. He requested a reliable and cost-effective solution for level control and limit control in his storage silos containing plastic components during the filling process. The system should support the automatisation of the material disposition for the storage silos.

Our Solution

For the level control of the silos containing PVC granular the electromechanical sensor NivoBob NB 3100 was chosen. It was important to have an easy commissioning and a reliable system The NivoBob works perfect in plastic granulars and also powders, because it is independent from the dielectric constant of the solid and other bad conditions like dust, sticky material or high humidity. The UWT NivoBob solved the problems, the customer had with contactless sensors and guarantees now the correct function of the plant. With the rotating paddle switch Rotonivo RN 3000 the full- and empty detection in the silos is realized. It always delivers reliable signals for the control system.
