At present, the current situation of the application of electronic weighbridge in China is not optimistic. We know that the weighing sensor and weighing indicator are the core components of the electronic weighbridge, and they have shown a diversified development trend, including imported and domestic ones, with a wide variety of models. As far as the sensor and display of the weighbridge are concerned, localization is the mainstream direction. At the same time, the localization process of the components of the electronic weighbridge and other electronic devices is also increasing. With the popularization of electronic weighbridge and the addition of localization trend, it is bound to present problems such as quality and inaccurate weighing in the process of using electronic weighbridge.
1) Indication out of tolerance
It means that the indication error of the electronic weighbridge is greater than the maximum allowable error of the national verification regulation. Simple indication error out of tolerance cannot be said to be a fault. Because after any kind of measuring instrument works for a period of time, Electronic weighbridge manufacturer Some functions have a certain amount of change. After the electronic weighbridge is debugged, its various metering functions are within the allowable error range, and the error will change after long-term use. The electronic weighbridge design may show that the indication error is greater than the allowable error in use, that is, "out of tolerance", which is difficult for the operator to find, as long as the calibration personnel of the measurement department verify with standard weights.
2) Problems caused by environmental problems
One of the main reasons is that the environmental sanitation of the electronic weighbridge application site is poor. The details of the electronic weighbridge, such as the long-term weighing of bulk materials, debris and dust enter the bottom of the scale platform or reptiles enter the interior of the surface. When encountering a humid climate, debris and dust are conductive due to moisture absorption. The electronic weighbridge features cause component or circuit problems, and sometimes it may burn components. Such problems generally appear abnormal.
3) Faults caused by sensor problems
The electronic weighbridge is generally used in parallel with 4~10 sensors, and the error is generally less than 0.02% FS. The sensor damage is mostly caused by weighing overload, improper use, or the internal quality of the sensor (patch, insulation, etc.). Therefore, it is necessary to strengthen the maintenance of sensors.
