High-precision weighing sensor for automation
| The WM-Ex weighing modules are specifically designed for the use in automated processes in hazardous environments (ATEX Zone 1; FM Class I, Div. 1). Speed, ruggedness, precision and direct connectivity are the key features of this product range. METTLER TOLEDO offers herewith an attractive product to meet the current market trend towards decreasing sample sizes with increasing quality- and precision requirements - also for hazardous applications. Such specifications are typically found in pharmaceutical, chemical or cosmetics labs and production sites where precise filling processes must be performed in hazardous environments. In the automotive field, similar conditions exist in airbag component production and e.g. in ignition system testing facilities. |
