由于计价器是在极其恶劣的环境条件下工作的,而在影响计价器性能及正常工作的各种因素中,干扰是最为显著的,也是最难克服的一个因素。它可以以电磁场的形式由空间侵入计价器主机,也可以从供电电瓶电压端以浪涌电压形式侵入,还可以因计价器接地不良,以及传感器输入端等侵入。造成的后果是计价器计 As the meter works under extremely harsh environmental conditions, interference is the most significant and one of the most difficult to overcome among the various factors that affect meter performance and normal operation. It can be in the form of an electromagnetic field invaded from the space meter host, you can also from the supply voltage of the battery intrusion in the form of surge voltage, but also due to poor meter ground, and the sensor input and other intrusion. The result is a meter
