高精度皮带秤的技术突破
摒弃传统皮带秤误差理论、创建新的误差理论，皮带秤主要误差源——皮带张力影响基本消除
传统皮带秤误差理论高精对皮带秤之“内力理论"
对一个单独的称重单元来说，其皮带张力的影响和传统皮带秤装态相同；在一个连续安装的称重阵列中，相邻单元的皮带张力影响相互抵消。即一个连续安装的称重阵列内部皮带张力影响力成为一种“内力"，对称重的影响为零，皮带张力的影响于阵列的出、入口处的单元。
12托辊皮带秤之“皮带效应理论"
“皮带效应"是指皮带的硬度、弱性等物理特性对称重产生的效应。在皮带张力的作用下槽形皮带呈半刚性状，当支承点高度不在一个准直面时，皮带沿运行方向会产生波浪、其对称重产生的影响称之为“皮带效应"。“皮带效应"的影响随皮带的硬度、物料的流量、环境的流量、环境的温度等因素的变化而变化。阵列式皮带秤通过检测、分析各单元采样值、建立一个“皮带效应"影响的数学模型并进行补偿修正。在“内力理论"指导下，采用与常规皮带秤截然不同的设计理念，称重单元整体结构十分，特别适合在恶劣工况下长期工作，对提高皮带秤的长期稳定期稳定性起到了关键作用。
单元使用一只称重传感器，支承两组称重托辊组采用的高抗弯性能结构设计结构简便，重量轻，现场安装快捷、方便称重托辊组采用皮带机原有托辊组日常工作中免维护

The stiffness of the weighing unit is greatly reduced, the weight is reduced and the influence of the belt tension change is reduced effectively. No impact on the use of roller materials for trade settlement and the more important bulk material measurement are expert system remote diagnosis, troubleshooting, remote early diagnosis, early warning, removal of the use of accuracy up to 0.2%, truly up to 0.2 class measurement requirements, stability period of more than 6 months. It is equipped with unique tracking to avoid zero point deviation system, each sensor alone AD detection, fault judgment, super-differential culling and other functions, so that the belt scale long-term high-precision stable operation. The real realization of high precision, self-check, maintenance-free, so as to ensure the accurate measurement of belt scales.

The Theory of Belt Effect on 12 Roller Belt Scale “belt effect" refers to the belt hardness, weakness and other physical properties of the symmetry of the effect. Under the action of belt tension, the groove belt is semi-rigid. When the height of the supporting point is not in a quasi-surface, the belt will produce waves along the running direction, and the effect of its symmetrical weight is called "belt effect ". The influence of "belt effect" varies with the hardness of the belt, the flow rate of the material, the flow rate of the environment, the temperature of the environment and so on. The array belt scale can be compensated by detecting, analyzing the sample value of each unit, establishing a mathematical model of the influence of "belt effect ". Under the guidance of "internal force theory ", adopting the design idea which is very different from the conventional belt scale, the whole structure of weighing unit is very unique, especially suitable for long-term work under bad working conditions, which plays a key role in improving the long-term stability of the belt scale. The unit uses a weighing sensor to support the two groups of weighing rollers with a unique high bending resistance structure. The structure is simple, the weight is light, and the field installation is quick and convenient. Force weighing sensor The weighing sensor used in the belt scale is a special-made sensor successfully studied by many parties. The sensor has many excellent performance indexes, such as anti-level force and partial load, and the overall performance is greatly improved.
