還應(yīng)考慮驅(qū)動(dòng)軸的縱向膨脹。自從這種膨脹通常由花鍵承擔(dān),這些花鍵也必須進(jìn)行潤滑。癥狀是:
信號的不穩(wěn)定性,例如在慢速運(yùn)行期間信號的跳躍。
6.5稱重傳感器、接線盒和裝電線
稱重傳感器非常堅(jiān)固,能夠承受高過載。壓力傳感器的數(shù)據(jù)
不會(huì)緩慢變化,而是逐步變化,通常與磨機(jī)中的事件相關(guān)。過分的
過載通常會(huì)導(dǎo)致零點(diǎn)永久偏移。
接線盒接觸不良會(huì)導(dǎo)致間歇性故障。靈敏度和零點(diǎn)都可能變化。
檢查所有螺釘端子。不要使用壓接至連接線的針腳,因?yàn)檫@些針腳通常有效過了一段時(shí)間就松了。
電纜,尤其是稱重傳感器的電纜,是最容易受到損壞的部分。
由于稱重傳感器繞組的電阻較低,因此很容易檢查稱重傳感器和電纜
來自控制單元。
一次繞組的電阻的典型讀數(shù)為1Ω,二次繞組的輸出阻抗為1-3Ω。
電纜或稱重傳感器中的絕緣故障可能導(dǎo)致靈敏度不正確或零點(diǎn)不穩(wěn)定。
當(dāng)稱重傳感器電路在可斷開端子處與接地和控制單元隔離時(shí),很容易測量與控制單元的絕緣。
如果電纜布線不正確,可能會(huì)受到其他電纜的干擾。

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.
