Operating principle and use
The Belt Scale is a weighing machine designed to acquire continuous material flow handled by a belt conveyor and by the integration of flow rate to determine the totalized amount of material.
The weight of the material on a belt length called “weighing length” is measured by one or two Strain Gauge Load Cells. The belt speed is measured by an incremental encoder or a proximity detector located on the conveyor’s driven drum
The SRT Belt Weigher was designed by SAUTELMA to meet the high accuracy required by their customers. The weight collection system incorporates 2 parallel sets of flexures supported by one or two strain gauge load cells. The design of the weight collection system ensures that the weight is transferred correctly into the load cell, to optimise the weighing performance.
The SRT belt scale can have single idler or double idler scale (SRT/1R et SRT/2R)
It consist of three main parts :
- Weight collection system model SRT
- Load cells, speed detector and signal processing unit
- Digital electronics control system
