The electronic belt scale is designed and manufactured for measuring and weighing bulk materials during the process of belt conveyor transportation. It is an efficient automatic weighing instrument that is widely used in various industrial production, material transportation, sales settlement, and port trade. It plays an important role in production control and economic accounting.
Therefore, the high and stable measurement accuracy of electronic belt scales is of great significance. Without achieving measurement accuracy or maintaining stable accuracy, its function and role cannot be discussed. However, in practical applications, electronic belt scales may encounter problems such as inaccurate and unstable measurement. Understanding the reasons for inaccurate measurement can be helpful for selecting, installing, debugging, and maintaining electronic belt scales.
1、 Product related reasons
The design structure, manufacturing quality, application materials, and usage technology of electronic belt scales can all affect the measurement accuracy they can achieve.
Regarding the design structure, the multi roller belt scale can achieve higher accuracy than the single roller belt scale, the fully suspended belt scale can achieve higher accuracy than the lever belt scale, and the unit combination matrix belt scale is a new type of high-precision belt scale. Generally speaking, under the same application conditions, it can achieve higher accuracy than other types of belt scales.
Regarding the prevention of processes and materials, it directly affects the quality and adaptability of belt scale components. For example, stainless steel material has better seismic and impact resistance, as well as anti-corrosion and rust prevention, which can better adapt to industrial environments; The rectangular steel pipe structure can effectively reduce the horizontal surface of the belt scale frame and minimize dust accumulation.
Regarding application technology, it directly affects the performance, accuracy, and operational use of belt scales. For example, digital sensors have stronger anti-interference ability compared to analog sensors; Compared to ordinary integrators, smart meters have more functions such as online monitoring, intelligent diagnosis, and one click calibration.
In short, if the electronic belt scale itself is not of high quality and the technology is not advanced or mature enough, it directly affects its accuracy, let alone maintaining stability in practical applications.
2、 Reasons for installation and debugging
Installation and debugging are the direct factors that affect the accuracy of measurement in the application process of electronic belt scales. It can be said that the accuracy and stability of belt scale measurement depend partly on its own quality and performance, and almost half on installation and debugging. If the belt scale is not installed correctly and reasonably, such as incorrect installation position, high vibration, electromagnetic interference, even the best performance and highest quality belt scale cannot truly achieve its optimal application effect.
3、 Mechanical equipment reasons
The main mechanical equipment is belt conveyors, which is the most common reason reported by Guonuo's after-sales engineers. Belt conveyor vibration, large changes in belt tension, and severe belt damage are common causes.
Therefore, users should try to avoid the above problems as much as possible when using electronic belt scales, and avoid installing large vibration machinery around the electronic belt scales and replacing damaged belts in a timely manner.
4、 Environmental reasons for use
The usage environment mainly includes working environment and natural environment. The former is mainly due to the fact that electronic belt scales are mostly used in industrial environments, which may have factors such as high dust accumulation, mechanical vibration, electromagnetic interference, etc; The latter is mainly due to harsh environments such as wind and rain in the natural environment, as well as large temperature changes that affect sensor components.
5、 Human operation reasons
According to feedback from Guonuo's after-sales engineers, many users' electronic belt scales have inaccurate measurements during use because they did not follow the training instructions.
For example, irregular calibration, and even not re calibrating after replacing the belt; The belt scale has been put into use, but welding and other operations are being carried out nearby; Not conveying materials according to the established range, suddenly increasing or decreasing material flow, far exceeding/far below the range; Personnel or heavy objects are weighed in the area using a belt scale.
