How to prevent various electromagnetic, meteorological conditions, and lightning impacts on the accuracy of scales With the rapid economic development, the use of scales is very wide, whether in industry, agriculture, or in daily life, education and scientific research and other fields, everywhere Weighing scales. However, in the design and use of ground scales, there is a problem of how to make its measurement accuracy the highest. And many disturbances have affected the measurement accuracy of ground scales, such as: radio frequency interference, electrostatic induction interference, leakage current induction interference, including various electromagnetic , weather conditions, lightning, etc. will affect the accuracy of the scales often listen to customers call and say, my electronic pounds are not allowed, when the weight is always the number of hops, and later my company's technical staff in the past looked and found The original was installed by other people's interference signal equipment! And a large number of interference has been affecting the measurement accuracy of electronic pounds, such as: RF interference, electrostatic sense solutions are:
1, using isolation transformer 2, the implementation of power supply packet power.
3, the use of high anti-jamming power.
4. Insert an interference controller designed according to the principle of spectrum equalization on the input end of the instrument's AC power supply to distribute the energy of the spike voltage concentration to different frequency bands, thereby weakening its destructiveness and thus suppressing the influence of spike interference.
The formation of interference problems is due to the existence of interference sources. The principle of anti-jamming is to suppress interference sources. The noise emitted by these sources of interference affects the instrument system through certain coupling channels. In order to avoid and reduce the influence of interference, the anti-interference ability should be considered when designing the instrument, and it is equally important to find and take measures to eliminate the interference source. In order to prevent the spread and coupling of interference, commonly used measures to suppress interference sources include: twisting, shielding, grounding, floating, balancing, filtering and isolation of signal conductors.
