PFEA1130张力传感器
Profibus测量范围
用户定义的缩放Profibus测量范围和负载划分可根据用户需求进行调整。Profibus测量范围Profibus测试范围（正常运行期间估计的卷筒纸张力）是用户输入的参数。用户更改测量范围值后，更改称重传感器标称负载不会影响Profibus缩放。最低有效位的值定义为负载划分。负载分配负载分配是将在Profibus上使用的分辨率。负载分配值由PFEA113计算，并取决于设置的测量范围。测量范围被划分为2001-5000范围内的有限数量的划分。负载划分值=一个划分，仅包含一个有效数字（1、2或5）。Profibus最多可处理-32768至+32767（216）个分区。
示例1：
a.Profibus测量范围（由用户设置）=15 500 N（正常操作期间的估计卷筒纸张力）b.通过PFEA113计算的负载分配=5 N（Profibus上最低有效位的值）c.Profibus测试范围/负载分配=15500/5=3100（测量范围分为3100个部分）示例2：如果示例1中的负载分配5 N不够，可以调整负载分配。这可以通过将杂项菜单中的MeasuringRange设置（减小）为一个提供足够负载分割（分辨率）的值来实现。a、 测量范围=9000 N（新的，测量范围的较低设置）b.通过PFEA113计算的新负载分配=2 N（Profibus最低有效位的新值）通过PFEA114中的设置9000 N，Profibus测量范围0–15500 N（分为7750个部分）仍可使用，现在负载分配（分辨率）为2 N。通常，在正常操作期间不需要将测量范围设置为低于估计的幅材张力的1/3。对于给定的负载分配，可通过Profibus传输的最大值为：–最大值=负载分配x 32767注：用户更改测量范围值后，返回默认比例的唯一方法是使用杂项人员中的设置出厂默认值功能
Profibus measuring range
User defined scaling Profibus measurement range and load division can be adjusted according to user requirements. Profibus measurement range Profibus test range (estimated web tension during normal operation) is a parameter entered by the user. After the user changes the measurement range value, changing the nominal load of the load cell will not affect the Profibus scaling. The value of the least significant bit is defined as the load partition. Load distribution Load distribution is the resolution that will be used on Profibus. The load distribution value is calculated by PFEA113 and depends on the set measurement range. The measurement range is divided into a limited number of divisions in the range 2001-5000. Load partition value=a partition containing only one significant number (1, 2 or 5). Profibus can handle up to - 32768 to+32767 (216) partitions.
Example 1:
a. Profibus measurement range (set by the user)=15 500 N (estimated web tension during normal operation) b Load distribution calculated by PFEA113=5 N (value of least significant bit on Profibus) c Profibus test range/load distribution=15500/5=3100 (the measurement range is divided into 3100 parts) Example 2: If the load distribution 5N in Example 1 is not enough, you can adjust the load distribution. This can be achieved by setting (decreasing) the MeasuringRange in the Miscellaneous menu to a value that provides sufficient load division (resolution). a. Measuring range=9000 N (new, lower setting of measuring range) b The new load distribution calculated by PFEA113=2N (the new value of the least significant bit of Profibus). By setting 9000N in PFEA114, the Profibus measurement range 0 – 15500N (divided into 7750 parts) can still be used. Now the load distribution (resolution) is 2N. Generally, it is not necessary to set the measuring range below 1/3 of the estimated web tension during normal operation. For a given load distribution, the maximum value that can be transmitted through Profibus is: – maximum value=load distribution x 32767 Note: After the user changes the value of the measurement range, the only way to return to the default proportion is to use the function of setting factory default values in miscellaneous personnel
