From Superman to lasers
Non-contact level sensors provide many benefits to the cement producer. These level measurement devices use 3D scanners, laser or radar technologies to ensure accurate monitoring of product levels. BinMaster compares the different technologies. By Jenny Nielson Christensen, BinMaster, USA.
For very large silos, two or more 3D scanners can be used to measure and map the material
Cement manufacturers find non-contact level sensors attractive for a number of reasons. Firstly, as nothing comes into contact with the material, there is no risk of equipment interfering with the process or rogue parts breaking off and getting stuck in equipment or contaminating materials. Secondly, they provide continuous level measurement for optimising inventory and preventing silos from running empty. No cement manufacturer wants to risk a bad batch due to missing key materials.
