3AUA0000110430热电偶模块,BCU-12怎么使用
称重传感器测量水平力。负载电池可以在两个方向上测量。应用的垂直未测量力，不会影响水平测量。有一个来源水平力，腹板张力产生的力（皮重重量在测量方向上没有分力）。参见图中的力计算。
将总垂直力FRtot除以2，得到每个称重传感器的所需容量。
请勿为过载目的而加大ABB称重传感器的尺寸因为称重传感器具有足够的过载能力。单测力传感器测量的力计算在某些情况下，仅在一个位置安装一个称重传感器即可测量张力卷结束。然而，应在两端支撑辊。
3AUA0000110430热电偶模块D、 7.1最常见、最简单的解决方案最明显、最简单的解决方案是水平安装，腹板均匀分布以卷为中心。
只要轧辊两端都有支撑，第D.6节“安装”中给出的计算备选方案，计算力和计算包裹增益是有效的。请注意，输出信号是一个求和。
注意事项单个称重传感器测量的精度在很大程度上取决于可以确定力的中心。由于横向应力分布一般有点不均匀，这不容易做到。称重传感器
然而，将产生稳定且可重复的测量。
The load cell measures the horizontal forces. The load
cell can measure in both directions. The vertical applied
forces are not measured and do not influence the
horizontal measurement. There is one source of
horizontal forces, the force from the web tension (the tare
weight has no force component in measuring direction).
See force calculations in figure.
Divide the total vertical force FRtot by two to get the
required capacity of each load cell.
Do not oversize an ABB load cell for overload purposes
as the load cell has sufficient overload capacity.Force Calculation for Measurement with a Single Load Cell
In some cases, it is sufficient to measure the tension with only a single load cell mounted at one
end of the roll. The roll should nevertheless be supported at both ends.
D.7.1 The Most Common and Simple Solution
The most obvious and simple solution is horizontal mounting with the web evenly distributed
and centered on the roll.
As long as the roll is supported at both ends, the calculations given in Section D.6, Mounting
Alternatives, Calculating Force and Calculating Wrap Gain are valid. Note that the output signal
is a summation.
NOTE
The accuracy of a single load cell measurement is highly dependent on how well
the center of force can be determined. Since the cross-directional stress
distribution generally is somewhat uneven, this is not easily done. The load cell
will, however, produce a stable and repeatable measurement.
