对绞双屏蔽电缆在抗电磁干扰中的应用

The application of a twist cable with double shield to anti-electromagnetic interference

该文描述主蒸汽压力测量结果出现偏差的现象,查找电磁干扰产生的原因,并对测量回路进行了数理分析,验证电磁干扰是导致测量产生误差的原因,进而引出对绞双屏蔽电缆的使用和使用效果总结。

This paper describes some phenomena about the measurement deviation from the mainsteam pressure,and makes a mathematic and physical analysis of the measuring circuit to find out that the electromagnetic interference causes the measurement deviation, thus adopting a twist cable with double shield to remove such a bad effect.
