瑞士ABB压头QGPR104 QGPR102的应用范围

包括压头在内的标准电气设备构成了从0.1至1.6 MN的额定力的力测量系统。

QGPR102/104压头构成设备的力传感单元。形状为环形，适合安装在要测量轴向力的轴上，例如安装在轧机螺杆螺母和轧机机架之间的轧机上。在这种情况下，使用两个压头，每一个在辊的一端。由于它们的位置，压头感知作用在磨机机架上的主要力量。

QGPR 102/104压头的典型应用领域是在管道和管道磨机中，特别适用于（金属）管道挤压和管道矫直机器的安装。 QGPR 102/104压头也可以用于平面轧机，其轧制力的大小小于可用其他zui小可用的ABB辊力测力传感器测量的力的大小（即当轧制热轧或冷轧更小的尺寸）。

由于QGPR104压头的安装高度较小，因此特别适用于压头测量方向的可用空间太小而无法使用QGPR 102称重传感器的场合。

The standard electrical equipment, including the load cells, constitutes a force measuring system for nominal forces from 0.1 up to 1.6 MN.

QGPR 102/104 load cells constitute the force sensing units of the equipment. These are annular in shape and are therefore suitable for installation on shafts where the axial forces are to be measured, e.g., in rolling mills where they are installed between the mill screw nuts and the mill stand. In this case, two load cells are used, one at each end of the rolls. Due to their location, the load cells sense the main forces acting on the mill stand. See figure Load cell location in a mill stand.

Typical application area of QGPR 102/104 load cells are in pipe and tube mills particularly for installation in (metallic) pipe extrusion and pipe straightening machines. QGPR 102/104 load cells can also be used in flat rolling mills where the magnitude of the roll forces is smaller than the force magnitudes that can be measured with other smallest available ABB Roll Force load cell types (i.e. when rolling hot or cold strips of smaller dimensions).

Due to the smaller installation height of QGPR 104 load cells, they are particularly suitable for installations where the available space in the measuring direction of the load cell is too small for using QGPR 102 load cells.

 

瑞士ABB压头QGPR104 YM114002-AA测量原理

Pressductor®技术是基于负载单元核心材料的磁弹性特性的变化。材料的磁性的负载相关变化以这种方式用于在负载单元核心中的次级测量绕组上感应电压。

压头的核心由许多圈组成。这些圈是由缠绕在内圈上的磁弹性板制成的。一个单独的测量区域由一个转盘上的四个孔组成，带有相关的励磁和测量信号线圈。

初级励磁绕组提供有特殊的交流电，在相邻的钢中产生磁通量。只要没有负载施加到换能器元件上，在标准激励的次级信号绕组周围就不会产生净磁通量。当传感器暴露在测量方向上的力时，钢中的磁弹性变化将允许磁通量并入次级绕组，从而引起与施加的力成比例的交流电压。

Pressductor® technology is based on the change of the magneto-elastic properties in the material which the load cell core is made of. The load-dependent change of the magnetic properties of the material is in this way used for inducing a voltage over a secondary measurement winding in the load cell core.

The core of a load cell consists of a large number of turns. The turns are made of magneto-elastic plate winded around an inner ring. One single measuring zone will consist of the four holes in one turn plate with associated excitation and measurement signal windings.

The primary excitation winding is supplied with a special alternating current, creating a magnetic flux in the adjacent steel. As long as no load is applied to the transducer element, no net magnetic flux will occur around the secondary, signal, winding at the standard excitation. When the transducer is exposed to a force in the measurement direction, the magneto-elastic change in the steel will allow the magnetic flux to incorporate the secondary winding, inducing an AC voltage proportional to the applied force.
