摘要
在称重传感器使用过程中常出现传感器过冲、过载等现象,容易造成传感器机械形变过载,输出信号超出称重仪表检测的量程,一般以报废处理。经实验室研究发现,大部分过载的称重传感器其内部电路完好,只是机械弹性体不能恢复到原来的状态。通过施加反向的作用力使其形变,基本恢复到原来差不多的零点电压对其进行修复,使传感器输出电压进入称重仪表正常使用电压范围内,得以继续使用。通过对过载29%损坏的称重传感器修复至量程范围的5%以内,表明了该方法可行,配备了自动修复软件和机构,可实现自动修复,具有操作简单、修复程度较高的特点。
It is a common phenomenon that the load cell is overloaded which will cause the mechanical overload damage to it,because of misoperation.Then the Weight Indicator and controller couldn’t work correctly,because of the overvoltage offset on zero.The load cell will be abandoned by the problem.A method is proposed to recover the sensor offset around zero by putting a force to the load cell on the reverse direction,which the Weight Indicator and controller can work on the range.According to the test on lab,the method is practicable and easy to use with the auto repair software and mechanism.
