Reliable Measurement in Pigment Powder Silos Despite Dust
After being processed, finished pigment powders are conveyed into packing silos. To control the filling process, the levels in the silos need continuous monitoring, and high-level detection switch is used for safety shutdown in case of overfilling. The pigment powder is then filled into packaging via the bottom outlet.
Finished pigment powders often have a low dielectric constant and with a low bulk density they generate dust when they are moved to silos or extracted from them, that’s why 80 GHz Non-Contacting Transmitters or Guided Wave Radar are the recommended solutions.
