Level measurement for the grain industry

The challenge

A big grain mill in Southern Germany required a suitable measurement technology for its 30m high raw material silos. The ease of installation as well as the reliability and longevity of the measuring equipment was of great importance to our customer. For his storage silos he required a visualisation system providing accurate live data of the material content within each silo. Overfill protection for the silos using level limit switches was also a stipulated requirement.

Our solution

The Nivobob 4200, with its integrated tape cleaner, ensures precise and extremely reliable content measurement. Using the UWT visualisation system NT3500 each silo can be started and controlled individually and the operator is able to track the trend over a set time period. The overfill protection is provided by the capacitive limit switch CN4030.
