ABSTRACT:
Method and apparatus for measuring the weight per unit area and providing cross-sectional, longitudinal, and diagonal profiles of density or thickness of moving manufactured sheet products. The apparatus comprises a stationary radiation source, an array of detectors, and electronic means for processing the signals from the detectors to obtain a total cross-sectional, longitudinal, and diagonal profile of density or thickness of moving manufactured sheet products. The energy output of the radiation source remains constant during a measuring operation. The apparatus utilizes a line-up of individual radiation sources delivering constant radiation. Each individual radiation source generates an equal amount of radiation. The radiation transmitted from the individual radiation source is intercepted by a detector/electronic assembly after penetrating the sheet product. The detector/electronic assembly converts the intercepted radiation to electric signals. The electric signals from the detector/electronic assembly are transmitted by conductors to electronic interface unit, signal processor and numerical display units. The invention provides an apparatus comprising the radiation source, detector/electronic assembly, electronic interface and signal processor, digital computer and numerical display modules and a method of identifying the entire transverse profile of the moving sheet products.
