本附录描述了称重传感器安装的设计程序。
包括以下部分：•基本应用注意事项•设计称重传感器安装（分步指南）
•安装要求•力和缠绕增益计算–水平安装–倾斜安装–单侧测量
•安装称重传感器•技术数据•图纸–电缆图
–称重传感器延长电缆的安装说明–尺寸图–装配图
5X00062G01电子模件C、 2基本应用注意事项每个应用程序都有自己的需要考虑的个人需求；虽然有一些基本的考虑因素往往会重复出现。
•涉及什么类型的过程（造纸、转化等）？环境是否要求（温度、化学品等）？
•张力测量的目的是什么；指示或闭环控制？是否有任何具体的精度要求？
•机器的设计是什么样的？是否有可能修改设计，为了安装最合适的称重传感器，还是机器设计是固定的？
•作用在辊上的力是什么（大小和方向）？它们可以通过重新设计来改变吗？如果彻底解决这些问题，安装很可能成功。
然而，需要测量精度的程度定义了以下要求：设计称重传感器装置。

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.
