-1- ABSTRACT OF THE DISCLOSURE Method and apparatus for detecting in conformity with process time mixing ratios in plastics and rubber com- pounding A method and an apparatus have been found, with the aid of which important properties can be determined during the extrusion of polymer melts: - continuous measurement of the density of pure polymers (density constancy) - plotting of p, v, T diagrams of plastics - determination of percentages by volume and weight in polymer/filler or polymer/reinforcing agent mixtures - determination of proportions by weight of pigment in masterbatch preparation - determination of measuring data for statements going further regarding mixing and thermal homogeneity of the material. Furthermore, the apparatus as a sensor is suitable as basic module for a closed control loop for monitoring and keeping constant proportions of filler.
