The 3DLevelScanner HE from BinMaster is designed for use in storage silos containing challenging materials such as clinker, alumina and fly ash. This newest model has an operating temperature range of up to 250 F (120 C) to accommodate higher temperatures that may be present when material that has been heated in the production process is conveyed into storage silos. Dependent on the diameter and height of the silo and the desired level of volume accuracy, one or more 3DLevelScanners is used. Each dust-penetrating, non-contact sensor sends pulses in a 70-degree beam angle, taking multiple measurements from the material surface and continually mapping the material surface to detect changes in level, account for uneven surface topography, and calculate a highly accurate volume estimate for the contents of the silo. The 3DLevelManager software reports the lowest and highest points detected and the average level based upon a weighted average of all of the measurements detected in the bin. For the MV and the MVL models, a colorful graphical representation will indicate where high and low spots exist in the silo.
