使用单个称重传感器进行测量
在某些情况下，仅在一个传感器上安装一个称重传感器即可测量张力
卷的末尾。
F、 6.1常见和简单的解决方案
明显和简单的解决方案是水平安装，腹板均匀分布
并以辊为中心。
只要辊子两端支撑，第F.5节中给出的计算结果相同
有效的
注
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
分布通常有些不均匀，这不容易做到。称重传感器
然而，将产生稳定和可重复的测量。

ation 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.
F.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 F.5 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.

Section F.6.2 Force Calculation when the Web is not Centered on the Roll
3BSE029382R0101 Rev C F-7
F.6.2 Force Calculation when the Web is not Centered on the Roll
Use the calculations below for horizontal and inclined mounting when the web is not centered
on the roll.
The applied force at the load cell will be proportional to the distance between the tension force
center and the load cell centerline.
Calculation procedure:
1. Horizontal or inclined mounting?
2. Calculate FR and FRT, see Section F.5
3. Use the following equations:
FR for single load cell =
FRT for single load cell =
FRtot for single load cell = FR for single load cell + FRT for single load cell
where:
L = Distance between load cell centerline and the opposite bearing centerline
a = Distance between tare force center and load cell centerline
b = Distance between tension force center and load cell centerline

F.7 Mounting the Load Cells
F.7.1 Preparations
Prepare the installation in good time by checking that the necessary documents and material are
available, as follows:
• Installation drawings and this manual.
• Standard tools, torque wrench and instruments.
• Rust protection, if additional protection is to be given to machined surfaces.
Choose TECTYL 511 (Valvoline) or FERRYL (104), for example.
• Locking fluid (medium strength) to lock fixing screws.
• Screws as listed in Table F-1 and Table F-2 to secure the load cell, and other screws for
bearing housings etc.
• Load cells, adapter plates, bearing housings, etc.
F.7.2 Mounting
The instructions below apply to a typical mounting arrangement. Variations may be allowed,
provided that the requirements of Section F.4 are complied with.
1. Clean the foundation and other mounting surfaces.
2. Fit the lower adapter plate to the load cell. Tighten the screws to the torque stated in
Table F-1 or Table F-2 and lock them with locking fluid.
3. Fit the load cell and the lower adapter plate to the foundation, but do not fully tighten the
screws.
4. Fit the upper adapter plate to the load cell, tighten to the torque stated in Table F-1 or
Table F-2, and apply locking fluid.
5. Fit the bearing housing and the roll to the upper adapter plate, but do not fully tighten the
screws.
6. Adjust the load cells so that they are in parallel with each other and in line with the axial
direction of the roll. Tighten the foundation screws.
7. Adjust the roll so that it is at right angles to the longitudinal direction of the load cells.
Tighten the screws in the upper adapter plate.
8. Apply rust protection to any machined surfaces that are not rust proof.
