摘要：
The method and device is directed to determine the strength based upon monitoring the variations in the intensify of a narrow beam of light transmitted through the sheet as the sheet moves perpendicularly through the beam.
Use is made of a sensor (10) consisting of two halves. The source half (12), disposed on one side of the sheet of paper (16), directs a beam of light through the sheet (16) whose formation is to be determined. The receiver half (14) is disposed on the opposite side of the sheet (16) and produces an electrical signal proportional to the intensity of the light which is transmitted through the sheet (16). The source half (12) includes a light source (18), such as a high intensity incandescent lamp (20), and a reflector (22) for directing the beam of light from the lamp (20) toward the sheet (16).
The determination is based upon the average basis weight, the local basis weight, the transmittance, the floc size and the line speed.
