MEASUREMENT CELL AND DEVICE FOR MEASURING THE ELECTRICAL PROPERTIES OF FILMS AND COATINGS AT HIGH TEMPERATURES

摘要

The invention relates to a cell for measuring the electrical resistivity of a film, which includes a receiving support surface, a plurality of electrodes (6, 8, 10, 12) having contact ends positioned to carry out an electrical measurement on a surface contact area (14) of the sample (3), and a means (16) for applying pressure to the electrodes (6, 8, 10, 12) in the direction of the sample (3), offset connection terminals (18, 20, 22, 24) of the electrodes, and electrical connections connecting the electrodes to connection terminals. The means for applying pressure (16) is made up of a shim (74) and elastic means (84, 86, 88, 90) for urging the contacts toward the sample (3).
