测压元件测量
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。.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C.5节“安装备选方案、计算力和计算缠绕增益”中给出的相同计算都是有效的。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。图C-2.横向应力分布张力电子设备，用户手册第C.6.2节“卷筒纸未在卷筒上居中时的力计算”3BSE029380R0001 C-7 C.6.2“卷筒纸不在卷筒上中心时的力的计算”当卷筒纸未居中时，使用下面的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C.5节“安装备选方案、计算力和计算缠绕增益”。3.使用以下等式：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
Load cell measurement
Force calculation measured with a single load cell In some cases, tension can be measured by installing a load cell at one end of the roll. However, both ends of the roll should be supported 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, section C The same calculations given in section 5 "Installation alternatives, calculated forces and calculated winding gain" are valid. 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. Figure C-2. Transverse stress distribution tension electronic equipment. Section C.6.2 "Calculation of force when the web paper is not centered on the reel" 3BSE029380R0001 C-7 C.6.2 "Calculation of force when the web paper is not centered on the reel". When the web paper is not centered, 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 procedure:
1. Horizontal installation or inclined installation? 2. Calculate FR and FRT, see Section C.5 "Installation Alternatives, Calculating Forces, and Calculating Winding Gain.". 3. Use the following equation: 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 the load cell centerline and the relative bearing centerline a=distance between the tare center and the load cell centerline b=distance between the tension center and the load cell centerline
