Abstract:
According to GB/T17626-4 standards，the hazards and the generating principle of EFT are analyzed in this paper． A weighing controller of DOUBLET BW2105 was tested by 3 ctest MODEL EFT-4002 pulse generator，which simulates the actual environment． Based on the mechanism of EFT and the structural features of weighing controller， EFT suppression filter was designed． Power coupling device was employed as well as grounding being improved，which reduced the accidental interference of the power side． The results showed that the immunity of the device was improved， which can passed the standard test of EFT．
