DUST LINE WITH OPTICAL SENSOR, AND METHOD FOR MEASURING THE COMPOSITION OF DUST

摘要

The invention relates to a dust line with an optical sensor and to a method for measuring a property of dust. The dust line according to the invention for transporting dust in an automated process comprises at least one optical sensor for monitoring the property of the dust. The optical sensor is arranged in an indentation of the dust line, said indentation being equipped with at least one gas inlet nozzle for removing the dust from the optical sensor. In the method according to the invention for measuring a property of dust in a dust line, dust is transported through a dust line. An optical property of the dust is measured using at least one optical sensor arranged in an indentation of the dust line, and ehe dust is then removed from the optical sensor by blowing in air using at least one gas inlet nozzle arranged in the indentation.
