安装备选方案
安装要求为了达到规定的精度、尽可能高的可靠性和长期稳定性，按照以下要求安装称重传感器。图C-1：安装要求动态平衡调心轴承允许轴向膨胀安装表面必须在稳定的基础内保持平整对于交付的螺钉，应使用正确的扭矩。垫片可放置在上转接板和轴承座之间，按照制造商的建议，对于其他螺钉，应放置在下转接板之间。适配器板的扭矩为24 Nm（18 ft-lb）。如果驱动测量辊，请始终咨询ABB，以确保G-2.5 ISO 1940-1级称重传感器的0.1 mm（0.004 in.）对准，至少满足测量辊的干扰。将称重传感器的风险降至最低的解决方案。垫片的正上方或下方不得放置板和基础。67 mm（2.64）a）c），且预期温度变化较大。mm（英寸）b）腹板a）最大0.5 mm（0.02 in.）b）最大1.0 mm（0.04 in.）c）最大5 mm/m（0.06 in./ft.）228（8.98）张力电子设备PFEA111/112，用户手册附录c PFTL 301E-设计称重传感器安装c-4 3BSE029380R0001
安装备选方案，计算力和计算缠绕增益c.5.1水平安装在大多数情况下，水平安装是最明显和最简单的解决方案。因此，称重传感器应尽可能水平安装。然而，如果机器设计需要倾斜安装称重传感器，或者如果腹板路径不能提供足够的水平力，请参见图，则允许倾斜安装，并且计算更为复杂（参见第C.5.2节，倾斜安装）。PFTL 301E称重传感器测量施加到其顶表面的水平力。称重传感器可以在两个方向上测量。不会测量垂直施加的力，也不会影响水平测量。水平力有一个来源；来自纸幅张力的力（皮重在测量方向上没有力分量）。参见图中的力计算。将总水平力FRtot除以2，得到每个测压元件所需的能力。由于称重传感器具有足够的过载能力，因此不要将ABB称重传感器过大。
Installation alternatives
Installation requirements In order to achieve the specified accuracy, as high as possible reliability and long-term stability, load cells shall be installed according to the following requirements. Figure C-1: Installation Requirements Dynamic balance self-aligning bearing allows axial expansion The mounting surface must be kept flat on a stable foundation For the screws delivered, the correct torque should be used. The gasket can be placed between the upper adapter plate and the bearing pedestal, and other screws should be placed between the lower adapter plate according to the manufacturer's recommendations. Torque the adapter plate to 24 Nm (18 ft lb). If the measuring roll is driven, always consult ABB to ensure that the G-2.5 ISO 1940-1 class load cell is aligned 0.1 mm (0.004 in.) to at least meet the interference of the measuring roll.

Installation alternatives, calculation of force and calculation of winding gain c.5.1 Horizontal installation In most cases, horizontal installation is the most obvious and simplest solution. Therefore, the load cell should be installed as horizontally as possible. However, if the machine design requires an inclined installation of the load cells, or if the web path does not provide sufficient horizontal force, see Figure, then an inclined installation is allowed and the calculations are more complex (see Section C.5.2, Inclined Installation). The PFTL 301E load cell measures the horizontal force applied to its top surface. The load cell can be measured in two directions. The force applied vertically will not be measured and the horizontal measurement will not be affected. The horizontal force has a source; Force from web tension (tare has no force component in the measuring direction). See the force calculation in the figure. Divide the total horizontal force FRtot by 2 to obtain the required capacity of each load cell. Since the load cell has sufficient overload capacity, do not make the ABB load cell too large.
