本附錄描述了稱重傳感器安裝的設計程序。
包括以下部分：?基本應用注意事項?設計稱重傳感器安裝（分步指南）
?安裝要求?力和纏繞增益計算–水平安裝–傾斜安裝–單側測量
?安裝稱重傳感器?技術數(shù)據(jù)?圖紙–電纜圖
–稱重傳感器延長電纜的安裝說明–尺寸圖–裝配圖
5X00062G01電子模件C、 2基本應用注意事項每個應用程序都有自己的需要考慮的個人需求；雖然有一些基本的考慮因素往往會重復出現(xiàn)。
?涉及什么類型的過程（造紙、轉化等）？環(huán)境是否要求（溫度、化學品等）？
?張力測量的目的是什么；指示或閉環(huán)控制？是否有任何具體的精度要求？
?機器的設計是什么樣的？是否有可能修改設計，為了安裝最合適的稱重傳感器，還是機器設計是固定的？
?作用在輥上的力是什么（大小和方向）？它們可以通過重新設計來改變嗎？如果徹底解決這些問題，安裝很可能成功。
然而，需要測量精度的程度定義了以下要求：設計稱重傳感器裝置。

C.2 Basic Application Considerations
Each application has its own individual demands that have to be considered; though a few basic
considerations tend to repeat themselves.
? What type of process is involved (papermaking, converting, etc.)?
Is the environment demanding (temperature, chemicals, etc.)?
? What is the tension measurement purpose; indication or closed loop control?
Are there any specific accuracy demands involved?
? What is the machine design like? Is there the possibility to modify the design,
in order to fit the most suitable load cell, or is the machine design fixed?
? What are the forces acting on the roll like (size and direction)?
Can they be altered by redesign?
If these questions are dealt with thoroughly, the installation is very likely to be successful.
However, the extent to which measurement accuracy is needed, defines the requirements when
designing a load cell installation.
