通用接头。还应考虑驱动轴的纵向膨胀。自从
这种膨胀通常由花键进行,花键也必须润滑。症状如下:
信号的不稳定性,例如在慢速运行期间信号的跳跃。
6.5称重传感器、接线盒和
装电线
称重传感器非常坚固,能够承受高过载。压力导管称重传感器的数据
不会缓慢变化,而是逐步变化,通常与工厂中的事件相关。过分的
过载通常会导致零点偏移。
接线盒接触不良会导致间歇性故障。灵敏度和零点都可能变化。
检查所有螺钉端子。不要使用压接在连接导线上的针脚,因为这些针脚通常会起作用
过了一段时间就松了。
电缆,尤其是至称重传感器的电缆,是容易受损的部分。
由于称重传感器绕组的电阻较低,因此很容易检查称重传感器和电缆
来自控制单元。
一次绕组电阻的典型读数为1Ω,二次绕组的输出阻抗为1-3Ω。
电缆或称重传感器中的绝缘故障可能导致灵敏度不正确或零点不稳定。
当称重传感器电路在可断开端子处与接地和控制单元隔离时,很容易测量控制单元的绝缘。
如果电缆布线不正确,它们可能会受到其他电缆的干扰。

versal joints. Longitudinal expansion of the drive shaft should also be taken into account. Since
such expansion is often taken up by splines, these must also be lubricated. The symptoms are
instability of the signal, for instance jumps in the signal during slow running.
6.5 Fault Tracing of Load Cells, Junction Boxes and
wiring
The load cell is very robust and can withstand high overloads. The data of a Pressductor load cell
does not change slowly, but in steps, usually in connection with an event in the mill. Excessive
overloading usually results in permanent shifting of the zero point.
Poor contact in the junction box causes intermittent faults. Both sensitivity and zero point may vary.
Check all screw terminals. Do not use pins crimped to the connecting wires, as these often work
loose after a time.
The cabling, especially the cable to the load cell, is the part that is most exposed to damage.
Since the resistance of the load cell windings is low, it is easy to check the load cells and cabling
from the control unit.
Typical readings are 1 Ω for the resistance of the primary winding and 1-3 Ω for the output impedance of the secondary winding.
Insulation faults in the cabling or the load cell may cause incorrect sensitivity or unstable zero point.
When the load cell circuits have been isolated from earth and from the control unit at the disconnectable terminals, it is easy to measure the insulation from the control unit.
If the cables are not routed correctly, they may pick up interference from other cables.
