Moisture Measurement for aggregates and sand using ...

Moisture sensors can measure moisture levels in materials being discharged from bins, on conveyor belts or within vibratory feeders. The sensors are placed directly in the flow of the material, and take 25 measurements per second as the sand or aggregate flows over the ceramic measurement surface. These measurements are then transmitted to the plant control system in real time. This allows the ...
