TRICONEX 8311N电子模件,8311N英文使用说明
有时有必要将称重传感器安装在因机械设计限制而倾斜
机器或需要适当的力分量应用于称重传感器。倾斜安装在测量方向并修改力分量
注意事项计算时,重要的是角度用正确的符号设置到方程式中相对于水平面。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。
TRICONEX 8311N电子模件6.1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。
只要辊在两端都有支撑,计算方法与第C.5节中给出的相同,安装备选方案、计算力和计算缠绕增益都是有效的。
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。
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.
C.6.1 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 same calculations given in Section C.5,
Mounting Alternatives, Calculating Force and Calculating Wrap Gain are valid.
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.
