The checkweighing controllers we supply provide fast and precise signal processing, as is required for the high throughput and short cycle times associated with checkweighers. The NMI Trade Approved devices possess an accuracy of 10,000 divisions and can process up to 800 weight measurements per second.

The controller stores target weights and tolerance zones for up to 99 different articles and connects to loadcells or scales of all types and weighing ranges, such as conveyor belt scales, roller track scales, and pit-mounted scales.

Operation can be dynamic or in start/stop mode, allowing for settling of the scale. Weight deviation from target, standard deviation or mean weight is displayed, with over and underweight items rejected via control signal outputs.
