Title: Optical mass measurement of moving fibrous material
Inventor: HESBERG SILKE DR
IPC: G01N33/36
Filed: 1997-06-19
Granted: 1999-03-11
Abstract: The mass of the fibrous material (8) is deduced from the amount of light transmitted as it passes between a light source (5.1) and a sensor (6.1). The instrument is arranged to operate in the nonlinear region of the relationship between light intensity and fiber mass as determined by an initial calibration. During calibration the light intensity of the source (5.1) is varied using a typical fiber strand and the transmission values are recorded. The operating region is then chosen to be outside the linear part of the characteristic in a region where the curvature is similar to the curvature of the known relationship between mass and light transmission. An Independent claim is also included for an instrument with a fiber channel (7) between frosted glass diffuser screens (9) fitted with light sources (5.1 to 5.10) on one side and light sensors (6.1 to 6.10) on the other. A processing unit (3) controls the light intensities, receives signals from the sensors, and stores the characteristic.  The processor (1) sets the controller in the required region and supplies output signals to the machine controller (10).
