水平安装
PFRL 101称重传感器可安装在0-360°的任何倾斜角度。但是，建议尽量减少除待测张力以外的力的影响。在大多数情况下，这意味着皮重力（垂直）垂直于测量力（水平）的方向。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D.6.2节，倾斜安装）。称重传感器测量水平力。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，即来自纸幅张力的力（皮重在测量方向上没有分力）。参见图中的力计算。将总垂直力FRtot除以2，得到每个测压元件的所需容量。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
用单个测压元件测量的力计算在某些情况下
只需在轧辊一端安装一个测压元件即可测量张力。然而，辊的两端都应得到支撑。D、 7.1最常见和最简单的解决方案最明显和最简单解决方案是水平安装，腹板均匀分布并以辊为中心。只要辊两端都有支撑，第D.6节“安装备选方案、计算力和计算缠绕增益”中给出的计算是有效的。注意，输出信号是求和。注：单个测力传感器测量的精度高度取决于测力中心的确定程度。由于横向应力分布通常有些不均匀，因此这不容易做到。然而，称重传感器将产生稳定且可重复的测量结果。
Horizontal installation
The PFRL 101 load cell can be installed at any tilt angle of 0-360 °. However, it is recommended to minimize the influence of forces other than the tension to be measured. In most cases, this means that skin gravity (vertical) is perpendicular to the direction of the measured force (horizontal). However, if the machine design requires an inclined load cell installation, or if the web path does not provide sufficient horizontal force, refer to the figure, then an inclined installation is allowed and the calculations are more complex (see Section D.6.2, Inclined Installation). The load cell measures the horizontal force. 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, that is, the force from the web tension (the tare has no component in the measuring direction). See the force calculation in the figure. Divide the total vertical 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
The force measured with a single load cell is calculated in some cases
Simply install a load cell at one end of the roll to measure the tension. However, both ends of the roll should be supported. D. 7.1 The most common and simplest solution The most obvious and simplest solution is to install horizontally, with the web evenly distributed and centered on the roll. As long as both ends of the roll are supported, D The calculations given in section 6 "Installation alternatives, calculated forces and calculated winding gain" are valid. Note that the output signal is summation. Note: The measurement accuracy of a single force measuring sensor depends on the determination of the force measuring center. Since the transverse stress distribution is usually somewhat uneven, this is not easy to do. However, the load cells will produce stable and repeatable measurements.
