GUIDE FOR LOAD CELL SELECTION GUIDA ALLA SCELTA DELLA CELLA DI CARICO Horizontal resultant Horizontal resultant is the best configuration for load cells, since it does not detect the weight of the roller. That configuration is recommended for low web tension. The result obtained refers to a single load cell. Downward resultant In the configuration with downward resultant the weight of the roller (P) supplies a positive signal which will be considered the tare. For a zero-set electrically subtract the roller weight value. Upward resultant In the configuration with upward resultant the weight of...

CF SERIES LOAD CELLS FLANGE MOUNTED / CELLE DI CARICO A FLANGIA Load cell with self-aligning locating bearing Cella con cuscinetto orientabile fisso The flanged load cells, CF series, fitted at the end of a measuring roller, can precisely detect the resultant of the forces generated by pulling of the material depending on the winding angles. The commercial success of these cells is due to the combination of several elements: a compact design, which allows them to be easily fitted in narrow spaces, their user-friendliness and a high reliability; the latter is due to the high quality standards...
