在這種情況下，傾斜角度會修改皮重負荷和力分量如圖所示。單測力傳感器測量的力計算
在某些情況下，僅在一個位置安裝一個稱重傳感器即可測量張力卷結(jié)束。然而，應(yīng)在兩端支撐輥。
B、 6.1最常見、最簡單的解決方案
最明顯、最簡單的解決方案是水平安裝，腹板均勻分布以卷為中心。
TRICONEX 3503EN熱電偶模塊只要輥的兩端都有支撐，計算方法與第B.5節(jié)中給出的相同，安裝備選方案、計算力和計算纏繞增益都是有效的。
注意事項
單個稱重傳感器測量的精度在很大程度上取決于可以確定力的中心。由于橫向應(yīng)力
分布一般有點不均勻，這不容易做到。稱重傳感器然而，將產(chǎn)生穩(wěn)定且可重復(fù)的測量。腹板不在輥中心時的力計算
當(dāng)腹板未居中時，使用以下計算進行水平和傾斜安裝正在滾動。
稱重傳感器上施加的力將與張力之間的距離成比例中心和稱重傳感器中心線。計算程序：

3、使用以下方程式：單個稱重傳感器的FR=單個稱重傳感器的FRT=單個稱重傳感器的FRtot=單個稱重傳感器的FR+單個稱重傳感器的FRT哪里：L=稱重傳感器中心線和相對軸承中心線之間的距離a=皮重力中心和稱重傳感器中心線之間的距離b=張力中心和稱重傳感器中心線之間的距離
Sometimes it is necessary to mount the load cell on an
incline due to mechanical design constraints of the
machine or the need to have a proper force component
applied to the load cell.
In this case, the incline angle modifies the tare load and
the force components as shown.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.
B.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 B.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.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:
