By measuring the distance between the product and the edge of the belt (freeboard), we can ensure that the maximum capacity of your system is always maintained, regardless of product type and surcharge angle of product on the belt. In addition, the system will run at maximum capacity, continuously.
Freeboard = Distance between the edge of the belt and product on the belt
CAS has recently implemented the control of a hydraulic gate on a rail car dumper. This was done using an indurad iLDR freeboard measurement radar sensor, to continuously maintain maximum unloading capacity.
Unlike most other sensor types, radar sensors are not affected by dust. The indurad iLDR sensor can withstand the dustiest conditions and has a feedback speed that can control hydraulic gate systems in real time.
