Automatic scales for batching according to OIML 61


Automatic scales are units appropriate for determining the mass of a body with utilization of the effect of the gravitational force on the body without operator interventions and to automatically follow a characteristic program sequence defined for the unit. Most of load cells sold by Siemens have been approved for use in scales requiring Class III verification in accordance with DIN EN 45501, and comply with OIML R60 to 3000d. We recommend our customers to use SIWAREX FTA as the electronics. In verified mode, this electronics has a high accuracy of 3 x 6000 divisions. The FTA can be used for batching, filling/sack filling and loading.
