Electronic products will inevitably be interfered by some external factors, making the data less accurate. The electronic weighbridge is often interfered by some external factors. How to solve or avoid interference factors?
The interference of electronic weighing apparatus means that various abnormal phenomena will appear during the use of electronic weighing apparatus. Despite the equipment quality problems, the abnormal phenomena caused by interference and grounding cannot be ignored. In serious cases, such as lightning strike, poor grounding, etc., will cause damage to equipment. We should fundamentally solve this problem. The main interference sources of electronic weighing apparatus are as follows.
Power interference. Power interference is in the form of surge. This phenomenon can be caused by lightning strike and electric charge introduced on the power line. Its harm is that it will cause fuse breakage, damage the printed circuit board, damage the bridge rectifier, etc. For such interference, a complete grounding system should be established so as to eliminate such interference.
Inductive interference. Inductive interference is caused by the destruction of magnetic field by inductance. This interference will cause long-term damage to the equipment. The way to deal with this interference is to shield the interference source. Now common operations are relatively passive, such as keeping away from interference sources or avoiding parallel wiring as far as possible.
Radio frequency excuse me. The manifestation of this interference is the inaccurate display of the electronic weighing instrument. For such interference, check whether the grounding system has applied long and thin wires, and whether the shielding function of wires is good. In addition, check whether the filter is normal.
AC interference. Such interference will damage equipment components. For such interference, it is an effective method to use a voltage stabilizing source that can filter interference.
