ABSTRACT OF THE DISCLOSURE The device for non-contact gauging of the thickness of various materials, such as paper, textiles, films and others utilizes the principle of non-contact measurement of said para- meter by means of a radioactive source and comprises a radiation source of charged radiation and a radiation detector located on one side of the material to be gauged. The invention is charac- terized by the fact that the radiation source and the radiation detector are interposed between the poles of a magnetic means. According to one of the embodiments of the invention, the mag- netic means comprises two pole sections of which one accommo- dates the radiation source and the other, the radiation detector, and the section accommodating the radiation source has pole shoes adapted to vary the distance therebetween. This device features a higher accuracy of measurements, makes it possible to use a low-active radiation source, simplifies radiation protection and reduces the mass and size of the device sensing unit.
