RN 3002 in KCl - concentrate
Our customer is one of the biggest producers of mineral fertilizers based on KCI worldwide. The company searched for a reliable limit detector of the KCI concentrate befor and after drying. In advance, they had used radioisotop-sensors but this and all the other measurement principles have caused failures. The challenge is the high humidity especially in cold seasons, deposit build-up, no further measuring points in the basin and very aggressive steam.
The rotating paddle switches of series Rotonivo RN 3002 have a robust design. The parts which have contact to the process are in stainless steel. They work independently from aggressive materials, are insensitive to deposit build-up and changing material attributes (the humidity before drying is 5%, afterwards 0,3%). It can be easily installed in a 1,5 inch socket.
