FIELD: the invention refers to measuring technique. ^ SUBSTANCE: the mode and the arrangement of non-invasive measurement of the parameters of extrusion material in the shape of a sleeve of a source of radiation of impulses. The source is located stationary inside the sleeve on its central axle, the light flow passed through the extrusion material is converted into electrical signals with the aid of photo detectors installed outside of the sleeve along the ring. The value of the electrical signals is measured and according to the measured values they define the parameter of the extrusion material according to an integrated or peak signal of the photo detectors and/or distribution of the parameter on the square of the material in correlation with the signals of the photo detectors. In quality of the parameter of the extrusion material they define its thickness and/or mass of the unit of square. The light flow passed through the material is preliminary divided on at least one supporting and at least on one measuring flows and their conversion is executed by photo detectors equipped with color filters with different spectral characteristics. The arrangement has also sensors designed for immovable location outside of the sleeve along the ring at the distance from it and on the level of the source of radiation. At that each sensor has a color filter optically connected with the source of radiation, a photo detector successively to which there are included an electrical signal processing block, an analog-digital converter and a calculator. The source of the impulse radiation represents itself as a gas-discharge impulse lamp. ^ EFFECT: increases speed of measurements and their reliability, and also simplification of the measuring process of the parameters of the extrusion material. ^ 19 cl, 3 dwg |
