 <description><![CDATA[&nbsp;&nbsp;谢谢一楼,&nbsp;&nbsp; 我公司另外一条生产线上的两枚检知探头可用了两年了哦!&nbsp;&nbsp;呵呵 ,&nbsp;&nbsp;最近产量高,我没机会去拆解此设备进行研究,我还以为是探头里面有感应线圈与钣材接触然后反馈一个电流信号在转换成数字信号的咧&nbsp;&nbsp;!&nbsp;&nbsp;小弟接触自动化生产线才一年多,还在学习阶段 ..]]></description>

 <description><![CDATA[多数是感应头的问题,其次是信号放大器的问题,有条件的话最好是成套换掉,检测厚度的一般都是超声波感应头,而超声波感应头的使用寿命是特别短的,好点的名牌产品标称使用寿命也就是10000小时(有的只有5000小时)左右]]></description>
