瑞士ABB壓頭QGPR104 QGPR102的應用范圍

包括壓頭在內的標準電氣設備構成了從0.1至1.6 MN的額定力的力測量系統(tǒng)。

QGPR102/104壓頭構成設備的力傳感單元。形狀為環(huán)形，適合安裝在要測量軸向力的軸上，例如安裝在軋機螺桿螺母和軋機機架之間的軋機上。在這種情況下，使用兩個壓頭，每一個在輥的一端。由于它們的位置，壓頭感知作用在磨機機架上的主要力量。

QGPR 102/104壓頭的典型應用領域是在管道和管道磨機中，特別適用于（金屬）管道擠壓和管道矯直機器的安裝。 QGPR 102/104壓頭也可以用于平面軋機，其軋制力的大小小于可用其他zui小可用的ABB輥力測力傳感器測量的力的大小（即當軋制熱軋或冷軋更小的尺寸）。

由于QGPR104壓頭的安裝高度較小，因此特別適用于壓頭測量方向的可用空間太小而無法使用QGPR 102稱重傳感器的場合。

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壓頭QGPR104 YM114002-AA測量原理

Pressductor®技術是基于負載單元核心材料的磁彈性特性的變化。材料的磁性的負載相關變化以這種方式用于在負載單元核心中的次級測量繞組上感應電壓。

壓頭的核心由許多圈組成。這些圈是由纏繞在內圈上的磁彈性板制成的。一個單獨的測量區(qū)域由一個轉盤上的四個孔組成，帶有相關的勵磁和測量信號線圈。

初級勵磁繞組提供有特殊的交流電，在相鄰的鋼中產生磁通量。只要沒有負載施加到換能器元件上，在標準激勵的次級信號繞組周圍就不會產生凈磁通量。當傳感器暴露在測量方向上的力時，鋼中的磁彈性變化將允許磁通量并入次級繞組，從而引起與施加的力成比例的交流電壓。

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.
