Level Scanner Copes with Challenging Silo Conditions
BinMaster Level Controls’ 3DLevel-Scanner HE is designed for use in stor-age silos containing challenging materi-als such as clinker, alumina and fly ash. This new version of the 3DLevelScanner has an operating temperature range of up to 250°F (120°C) and, according to BinMaster, is ideal for use where there are multiple challenges such as dust or high humidity and very large silos where the material surface in the bin may be uneven and difficult to measure. In prac-tice, dependent on the diameter and height of the silo and the desired level of volume accuracy, one or more 3DLevel-Scanners is mounted on the top of the silo in strategic locations determined by using advanced proprietary software. Each dust-penetrating, non-contact sen-sor sends pulses in a 70° beam angle, taking multiple measurements from the material surface and calculating a highly accurate volume estimate for the con-tents 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.
