传感器:

查找传感器故障步骤如下:在接线盒内用万用表检查正激励和负激励间电阻值(在接线盒内通向仪表的信号电缆接线柱上侧),其阻值大约为400Ω/传感器数。用万用表测量总输出端的正输出和负输出之间电阻,其阻值大约为2500Ω/截面数,如果发现阻值不对,按下一步继续查找。逐次断开传感器,用上述方法,测量正负激励端或正负输出端间阻抗值,查出损坏的传感器。如果这步查找没问题,则按下步继续查找。将砝码依次放在秤台各个截面上,如果发现哪个截面的示值不正确,则再将砝码放在这个截面的传感器角上,查出坏传感器。或者脱开某传感器的+ Si、一Si端,在不通电情况下测电阻值,应在350Ω左右。在通电情况下,测两端的直流电压,设传感器容量为K,它实际受到的力为F,则电压值应为12.5 x 2F/K(mV) 。
