The E 90/1 ATEX weighing instrument (stainless steel) is designed for installation in potentially explosive environments and is suitable for use in the many applications required by most of the chemical, pharmaceutical and paint industries. The complete digital programming of the instrument takes place directly from the front through 4 keys. The E 90/1 instrument has the peak hold function for dynamic weighings and it can be interfaced with the most common PLCs thanks to the Profibus-DP board which can be installed as an option directly in the instrument. The weighing instrument is compliant with the following regulations: EN50081-1, EN5002-2 for EMC; EN61010-1 for Electrical Safety; 94/9/EC for ATEX II 2 GD; EEx d IIB T6÷T4. PWS: 41/2012
