计算程序
当卷筒纸未在卷筒上居中时的力计算当卷筒纸不在卷筒上中心时，使用以下计算进行水平和倾斜安装。称重传感器上施加的力将与张力中心和称重传感器中心线之间的距离成比例。计算程序：1.水平安装还是倾斜安装？2.计算FR和FRT，参见第D.6节“安装备选方案、计算力和计算缠绕增益”。3.使用以下公式：单个测压元件的FR=单个测压传感器的FRT=单个测力元件的FRtot=单个测力元件的FR+单个测压单元的FRT，其中：L=测压元件中心线与相对轴承中心线之间的距离a=皮重中心与测压元件中心线之间的间距b=张力中心与测力元件中心线之间距离b a L皮重力中心称重传感器PFRL 101张力中心5 张力电子设备PFEA111/112，用户手册第D.8节安装称重传感器3BSE029380R0001 D-9 D.8安装称重传感器1.将轴承安装在称重传感器中。注意：使用不会损坏轴承或称重传感器的工具和材料。注：其中一个轴承用挡圈锁定到位，而另一个轴承仅压入正确位置，以允许轴向膨胀。
a、 将其中一个挡圈安装到称重传感器中。b、 如下图所示，布置一个反拉线。c、 将轴承压到正确位置。注：轴承座只有轻微的过盈配合，因此不应使用重力。d、 将另一个挡圈安装到称重传感器中。带定距环的固定轴承压紧外圈无定距环固定轴承松动轴承支撑支撑支撑支撑压紧外环定距环扣环张力电子设备PFEA111/112，用户手册附录D PFRL 101-设计称重传感器安装D-10 3BSE029380R0001 2。如有必要，安装定距垫圈和轴封。3.将内部测压元件盖放置到位，并将四个安装螺钉放入孔中。4.将称重传感器压到轴上（仅压轴承内圈）。5.将轴承的挡圈安装在轴上。将外盖放置到位。6.将测量辊连同称重传感器一起放置在机器上的正确位置。带有松动轴承的测压元件朝辊移动，以减少总长度，从而可以安装带有测压元件的测量辊。当辊就位时，将带有松动轴承的称重传感器拉回到其正确位置。7.使用四个安装螺钉固定每个称重传感器。（根据制造商建议拧紧扭矩）8.必要时调整轴封。
Calculation program
Force calculation when the web is not centered on the reel When the web is not centered on the reel, use the following calculation for horizontal and inclined installation. The force applied to the load cell will be proportional to the distance between the center of tension and the center line of the load cell. Calculation program: 1. Horizontal installation or inclined installation? 2. Calculate FR and FRT, see Section D.6 "Installation Alternatives, Calculating Forces, and Calculating Winding Gain.". 3. Use the following formula: FR of a single load cell=FRT of a single load cell=FRtot of a single load cell=FR of a single load cell+FRT of a single load cell, Where: L=distance between load cell center line and relative bearing center line a=distance between tare center and load cell center line b=distance between tension center and load cell center line b a L tare center load cell PFRL 101 tension center 5 tension electronic equipment PFEA111/112, User Manual, Section D Section 8 Installing the load cell 3BSE029380R0001 D-9 D.8 Installing the load cell 1. Install the bearing in the load cell. Note: Use tools and materials that will not damage the bearings or load cells. Note: One of the bearings is locked in place with a retainer ring, while the other bearing is only pressed into the correct position to allow axial expansion.
a. Install one of the retaining rings into the load cell. b. As shown in the figure below, arrange a reverse stay wire. c. Press the bearing to the correct position. Note: The bearing pedestal has only a slight interference fit, so gravity should not be used. d. Install the other retaining ring into the load cell. Fixed bearing pressure tight outer ring with distance ring No distance ring Fixed bearing loose bearing support support support support pressure tight outer ring distance ring retaining ring tension electronic equipment PFEA111/112, user manual appendix D PFRL 101 - Design load cell installation D-10 3BSE029,380R0001 2. If necessary, install spacer washers and shaft seals. 3. Place the inner load cell cover in position and place the four mounting screws into the holes. 4. Press the load cell onto the shaft (only the bearing inner race). 5. Install the retaining ring of the bearing on the shaft. Place the cover in position. 6. Place the measuring roll together with the load cell in the correct position on the machine. The load cell with loose bearing moves towards the roll to reduce the total length so that the measuring roll with load cell can be installed. When the roll is in place, pull the load cell with loose bearing back to its correct position. 7. Secure each load cell with four mounting screws. (Tightening torque according to the manufacturer's recommendations) 8. Adjust the shaft seal if necessary.
