TRICONEX 8311N電子模件,8311N英文使用說(shuō)明
有時(shí)有必要將稱(chēng)重傳感器安裝在因機械設計限制而傾斜
機器或需要適當的力分量應用于稱(chēng)重傳感器。傾斜安裝在測量方向并修改力分量
注意事項計算時(shí)，重要的是角度用正確的符號設置到方程式中相對于水平面。單測力傳感器測量的力計算在某些情況下，僅在一個(gè)位置安裝一個(gè)稱(chēng)重傳感器即可測量張力卷結束。然而，應在兩端支撐輥。
TRICONEX 8311N電子模件6.1最常見(jiàn)、最簡(jiǎn)單的解決方案最明顯、最簡(jiǎn)單的解決方案是水平安裝，腹板均勻分布以卷為中心。
只要輥在兩端都有支撐，計算方法與第C.5節中給出的相同，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(gè)稱(chēng)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。由于橫向應力分布一般有點(diǎn)不均勻，這不容易做到。稱(chēng)重傳感器然而，將產(chǎn)生穩定且可重復的測量。
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.
