Laser scanners provide a better picture
Level and flow specialists Allison Engineering have extended their KTEK range of laser-based instruments.
The development follows the introduction of a new 2-D volume flow scanner and a 3-D laser belt scanner. Both new products offer the important features and benefits of high accuracy, non-contact and continuous measurement.
The KTEK LM080 laser belt scanner provides continuous, non-contact M3/hr volumetric flow measurement of bulk solids lying on belts and conveyors, whilst simultaneously monitoring the belt speed. The result is a 2-D cross-sectional area of bulk material, while the belt speed provides a 4-20mA output which is scaled in cubic metres per minute.
Unlike other volumetric measuring technologies, such as gravimetric weighing, KTEK is unaffected by vibrations and so provides more accurate data. It provides accuracy within 2%; it is quick and simple to set-up, requiring no regular maintenance or re-calibration.
The LM080 is a rugged and competitively priced device particularly suited to measuring applications wherever bulk solids and granular materials are being conveyed and stored.
Meanwhile, the LM050 is a moving 3D laser scanner that provides continuous, non-contact three-dimensional measuring, or ‘mapping,’ of entire stockpiles. Each laser uses a large number of measuring points to ensure accurate profile imaging and automatic volume measurement to an accuracy of +/- 0.5%.
This device meets the increasing demand in industries where users are moving towards increased automation of production and inventory control. Benefits would include enhanced environmental control and the ability to provide improved fiscal valuation of bulk solid stocks, and therefore more accurate estimates of available ‘energy stock’.
