称重传感器安装设计分步指南
以下程序定义了设计称重传感器时需要考虑的主要因素安装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)。
称重传感器的尺寸和方向应符合以下准则:
a、 试着在称重传感器中获得不小于腹板张力10%的测量值测量方向!
1C31166G01模块b、 选择称重传感器尺寸,使其负荷尽可能接近其标称负荷!做不测量测量方向上张力的力分量FR,小于称重传感器标称负载的10%!
c、 如果过程中最大和最小张力之间的跨度较大,请选择称重传感器,使最大张力处于称重传感器扩展范围内(当适用)!
d、 建议测量的腹板张力分力至少为作用于称重传感器测量方向的皮重分力(辊重)。这个此建议的原因是称重传感器信号的稳定性,尤其是当系统在较大的温度范围内运行。
这意味着,如果FRT<Fnom的1/3,则FR应至少为Fnom的10%。
对于较大的FRT,建议最低FR至少为FRT的30%。检查称重传感器数据,以确保建筑物高度、横向力和轴向力的限制为未超过。设计基架和/或转接板。
Step-by-Step Guide for Designing the Load Cell Installation
The procedure below defines the main considerations involved in designing a load cell
installation.
1. Check load cell data so that environmental demands are met.
2. Calculate forces; vertical, horizontal and axial (cross directional).
3. Size and orientate load cell so that the guidelines below are met:
a. Try to achieve a measured value no less than 10% of web tension, in the load cell
measurement direction!
b. Select load cell size so that it is loaded as close as possible to its nominal load! Do
not dimension Force component of Tension in measuring direction, FR, for less than
10% of the load cell nominal load!
c. If the span between maximum and minimum tension in the process is large, select
load cell so that the maximum tension will be in the load cell extended range (when
applicable)!
d. The measured force component of web tension is recommended to be at least 30% of
tare force component (roll weight) acting in load cell measurement direction. The
reason for this recommendation is load cell signal stability, especially when the
system operates in a large temperature span.
This means that if FRT < 1/3 of Fnom, FR should be at least 10% of Fnom.
For larger FRT, lowest FR is recommended to be at least 30% of FRT. Check load cell data so that limits for building height, transverse and axial forces are
not exceeded.
4. Design base frame and/or adapter plates.
