Fast on-site checking of recovered paper bales by means of portable measuring devices

The PaperBaleSensor (PBS) is the first measuring system on the market permitting simultaneous and highly accurate measurements of the moisture, polymer, fibre and ash contents of recovered paper bales within just a few minutes. The only prerequisite is a simple drill hole of any depth which – unlike the previously required core drillings – can be made automatically within seconds, using simple equipment. The actual measuring is done by a lancehead-shaped sensor. The sensor scans the bore in the near-infrared wavelength range and calculates the shares of the components present according to a fixed routine.
