The weighing of small items at high throughput speeds calls for exceptional precision of all components involved. To ensure reliable processing, even the slightest deviation has to be detected with supreme accuracy. This demands a high degree of synchronized precision when feeding and removing the objects to be measured. The requirements of the industrial scale itself are even more stringent. Neither the conveyor belt nor the drive may cause any disturbing vibrations. Precisely controlled and smooth-running sine wave commutated DC-Servomotors are the perfect solution for such demanding tasks.
Industrial manufacturers often produce small, lightweight products in bulk. Fill quantities or completeness can then be conveniently measured using an industrial scale. In the majority of cases, they are mass-produced goods where both precision and high-throughput monitoring are critical for quality control. Weighing specialist Mettler-Toledo Garvens GmbH has developed its XS1 checkweigher specifically for this field of application. In cooperation with drive specialist FAULHABER, the weighcell was equipped with a smooth-running conveyor belt – including a controllable drive – that operates without adversely affecting the weighing process. Fast, jitter-free transport and precise weight detection are thus combined to provide high output performance.
