Electronic belt scales, as dynamic weighing instruments installed on belt conveyors, have evolved into various structural types to adapt to different working environments, conveyor conditions, and accuracy requirements. Among these, the relatively new fully suspended belt scale structure stands out as a high-precision option, commonly adopted in high-end, high-accuracy belt scales.
The scale frame of a fully suspended belt scale is a directly weighing structure with no mechanical levers. It leverages a special connection method for high-precision sensors, cleverly suspending the weighing frame within the conveyor space without any fulcrum points.
This eliminates the impact of intermediate force transmission on measurement accuracy, enhancing accuracy and the scale's environmental adaptability, as well as ensuring stability.
Due to varying user needs for accuracy, stability, operability, and changing working environments, fully suspended belt scales have different classifications, mainly including ICS-14 belt scales and matrix belt scales. Both feature directly loaded, fully suspended scale frames, but with significant differences.
The ICS-14 belt scale is an earlier fully suspended model, available in fixed structures as ICS-14A and ICS-14B. ICS-14A uses four sets of rollers, while ICS-14B uses three. Both employ four high-precision weighing sensors and can adapt to conveyor inclinations of ≤6°. Ideally, their verification and dynamic accuracies are consistent. However, in practice, ICS-14B, with fewer rollers and a simpler structure, is more suitable for shorter conveyors. Due to variable conveyor conditions, ICS-14A may perform better in terms of accuracy and stability.
The matrix belt scale is a highly advanced, high-accuracy belt scale. While also fully suspended, it features a single roller set, multiple high-precision sensors, and no crossbeam structure. Each roller set is an independent weighing unit, freely combinable to form a multi-roller matrix measurement platform. This design offers higher flexibility and stability, as weighing units operate independently, ensuring continued function even if one unit malfunctions.
The matrix belt scale is simpler, lighter, and less affected by its own mechanics during weighing. It is easier to transport, install, and maintain, adapting well to various harsh environments and conveyor conditions.
For short conveyors, fewer or even single weighing units can be used. The matrix belt scale also accommodates greater conveyor inclinations.
In summary, while both ICS-14 and matrix belt scales feature fully suspended frames and high accuracy, the ICS-14 has a fixed structure and higher installation requirements, whereas the matrix belt scale, with its modular weighing units, offers superior environmental adaptability, accuracy, and stability.
