Application of radar technology for measuring the levels of bulk materials in the cement industry |
||||||||||
|
Continuous determination of the levels of bulk materials in silos and storage halls, and also in crushers or clinker coolers, represents one of the challenges of the cement production process. High dust concentrations, extreme temperatures, severely abrasive stresses and difficult installation conditions make the measurements more difficult and often lead to high maintenance costs. At the end of 2004 VEGA Grieshaber KG introduced the first radar sensor, the VEGAPULS 68, to be developed specifically for level measurement of bulk materials. The great advantage of radar as a physical measuring principle is that it is scarcely affected by process parameters like dust or air-flow. Nor are the radar signals sensitive to high temperatures, so installation in klinker cooler is also a possibility. In addition to this the VEGAPULS 68 radar sensor is 1 000 times more sensitive than conventional equipment. The following examples show the potential applications for radar technology in a cement plant.
