设计程序
1关于本附录本附录描述了称重传感器安装的设计程序。包括以下章节：•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–称重传感器安装说明延长电缆-尺寸图-装配图B.2基本应用注意事项每个应用都有其各自的需求，必须加以考虑；尽管一些基本考虑往往会重复。•涉及哪种类型的工艺（造纸、转化等）？环境是否苛刻（温度、化学品等）？•张力测量的目的是什么；指示还是闭环控制？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，以便安装最合适的称重传感器，或者机器设计是否固定？•作用在辊上的力是什么样的（大小和方向）？它们可以通过重新设计来改变吗？如果彻底解决了这些问题，安装很有可能成功。
设计称重传感器装置
在设计称重传感器装置时，需要测量精度的程度决定了要求。张力电子设备，用户手册附录B PFCL 301E-设计称重传感器装置B-2 3BSE029380R0001 B.3称重传感器装置设计分步指南以下程序定义了设计称重传感器安装所涉及的主要考虑因素。1.检查称重传感器数据，以满足环境要求。2.计算力；垂直、水平和轴向（横向）。3.测压元件的尺寸和方向应符合以下准则：a.在测压元件测量方向上，尽量达到不小于10%卷筒纸张力的测量值！b、 选择称重传感器尺寸，使其负载尽可能接近其标称负载！测量方向FR上的张力力分量不得小于称重传感器标称载荷的10%！c、 如果过程中最大张力和最小张力之间的跨度较大，则选择称重传感器，使最大张力处于称重传感器扩展范围内（如适用）！d、 卷筒纸张力的测得力分量应至少为测量方向皮重（卷筒重量）的30%。e、 检查称重传感器数据，确保不超过建筑物高度、横向和轴向力的限制。4.设计底架和/或转接板。
Design procedure
1 About this appendix This appendix describes the design procedure of load cell installation. The following sections are included: • Basic application considerations • Design load cell installation (step-by-step guide) • Installation requirements • Force and winding gain calculation – Horizontal installation – Inclined installation – One side measurement • Installing load cells • Technical data • Drawing – Cable diagram – Load sensor installation instructions Extension cable – Dimensional drawing – Assembly drawing B 2 Basic application considerations Each application has its own needs, which must be considered; Although some basic considerations are often repeated. • What type of process is involved (papermaking, conversion, etc.)? Is the environment harsh (temperature, chemicals, etc.)? • What is the purpose of tension measurement; Indication or closed-loop control? Are there any specific accuracy requirements? • What is the design of the machine? Is it possible to modify the design to install the most suitable load cell, or is the machine design fixed? • What is the force acting on the roll (magnitude and direction)? Can they be changed by redesign? If these problems are completely solved, the installation is likely to succeed.
Design the load cell device
When designing a load cell device, the degree of measurement accuracy required determines the requirements. Tension electronic equipment, user manual Appendix B PFCL 301E - Step by step guide for designing load cell device B-2 3BSE029380R0001 B.3 The following procedures define the main considerations involved in designing load cell installation. 1. Check the load cell data to meet the environmental requirements. 2. Calculation force; Vertical, horizontal and axial (transverse). 3. The size and direction of the load cell shall comply with the following criteria: a In the measuring direction of the load cell, try to reach the measured value of not less than 10% of the web tension! b. Select the size of the load cell so that its load is as close to its nominal load as possible! The tension force component in the measuring direction FR shall not be less than 10% of the nominal load of the load cell! c. If the span between the maximum tension and the minimum tension in the process is large, select the load cell so that the maximum tension is within the load cell expansion range (if applicable)! d. The measured force component of the web tension shall be at least 30% of the tare weight (web weight) in the measuring direction. e. Check the load cell data to ensure that the building height, lateral and axial force limits are not exceeded. 4. Design the underframe and/or adapter plate.
