详情介绍:PFCL201CE 50kN 称重传感器 测压元件
这些单位是专为带钢张力测量在应用中，它是必要的或有利的，以确定垂直力分量。
由一整块不锈钢加工而成，它们对过载，冲击和冲击具有的耐受性，此外还具有对灰尘和腐蚀的高免疫力。
标准结构是高耐蚀不锈钢，内部组件是密封的。工厂任务版本可用于异常恶劣的环境，即镀锌或酸洗线。
测压元件安装在滚动轴承下，测量与安装面成直角的力。
来自带钢的反作用力与带钢张力成正比，通过辊子和轴承传递给测压元件。
测压元件通过接线盒连接到控制单元。控制单元将测压元件信号转换成与反作用力成比例的直流电压。根据所选择的控制单元，可以有两个单独的称重传感器(A和B)的模拟信号，称重传感器信号的总和(A+B)，和/或称重传感器信号之间的差(A-B)。
1.4.3测量原理
称重传感器只测量FR方向上的力。测量力可以是正的，也可以是负的。称重传感器通常安装在滚动轴承下。当有一条带材在轧辊上受张力时，张力(T)产生两个力分量，一个在测压元件的测量方向(FR)上，另一个在直角方向(FV)上。
测量力取决于张力(T)与测量辊周围的带材形成的缠绕角之间的关系。
PFCL201CE
These units are designed for strip tension measurement in applications where it is essential or advantageous to determine the vertical force component.
Machined from a single block of stainless steel, they have exceptionally high tolerance for overloads, shock and impact, in addition to high immunity to dust and corrosion.
The standard construction is of high resistant stainless steel with potted internal components. Mill-duty versions are available for exceptionally hostile environments in i.e. galvanizing or pickling lines.
The reactive force from the strip, which is proportional to the strip tension, is transferred to the load cells via the roll and the bearings.
The load cells are connected to the control unit via a junction box. The control unit converts the load cell signals to DC voltages that are proportional to the reaction force. Depending on which control unit is chosen, it is possible to have the analog signals for the two individual load cells (A and B), the sum of the load cell signals (A+B), and/or the difference between the load cell signals (A-B).
1.4.3 Principle of Measurement
The load cell only measures force in the direction FR. The measurement force may be positive or negative. The load cell is normally installed under the roll bearings. When there is a strip in tension over the roll, the tension (T) gives rise to two force components, one in the direction of measurement of the load cell (FR) and one at right angles (FV ).
The measuring force depends on the relationship between the tension (T) and the wrap angle formed by the strip around the measuring roll.
