我的称重仪表显示超载了怎么办
发布日期:2024-08-23 16:16:35

今天我们一个客户反馈说他们生产新安装的称重仪表显示了负超载,然后赶紧联系我们艾丽得技术售后,发现是他们的传感器接线接错了,然后及时更改过来,就完美解决了。为了方便大家及时解决称重显示仪表出现正超载、负超载或E00错误提示(传感器信号不在-30.5~30.5mV之间)这一类的故障问题,小编整理了一个表,大家对照问题和解决措施做出相应的调整哦,如还有不明了的地方,欢迎随时联系我们哦,第一时间为您服务。

故障位置

可能的故障分析与判断

预防及解决措施

传感器

传感器接线错误

检查传感器接线

在秤台进行焊接,烧坏传感器或仪表

更换传感器或仪表

过载或撞击使传感器发生永久性塑性变形

●秤体安装的时候应轻缓,安装后反复垫平,使每只传感器受力非常相近,避免某一个或几个传感器受力点悬空,如有可能,在秤体安装或运输时,先用假传感器或垫块代替

●正确选用传感器的量程,避免过载

●普通使用秤应避免冲击载荷,秤体本身就要承受冲击载荷(例如钢材秤)的,一定要设计好减震装置。传感器冲击过载后的主要特征有:

★弹性体明显变形,一般肉眼都可以看到

★传感器空载时零点输出较大,一般都在0.5mV/V以上

接线盒

接线盒进水

仪表可能会显示一很大的重量、正/负超载、无显示(激励电源短路,仪表自身保护)或E00错误提示等

电缆线

传感器到接线盒或仪表的接线错误

检查接线

仪表

仪表没有标定

标定仪表

仪表最大量程设置错误

重新设置仪表的最大量程和分度间距

仪表接线端子接触不良

重新接好线

仪表损坏

用备用仪表或模拟器观察,如果有损坏,更换仪表
