In many industrial settings, the best tool for short distance transportation of bulk materials is the belt conveyor, which can achieve continuous dynamic transportation of material flow.
During the transportation process of a belt conveyor, if it is necessary to grasp the weight of the material flow, an electronic belt scale is needed. It is mainly used to measure the flow rate of loose materials during the transportation process and accumulate the flow rate to obtain the total weight of the transported material.
Electronic belt scales are used for continuous, dynamic, and automatic weighing and measurement during conveyor transportation, and can be applied in many occasions such as cement plants, building materials factories, environmental protection, steel, grain, etc. Due to the special application scenarios and harsh application conditions, coupled with the fact that electronic belt scales rely on highly sensitive weighing sensors and speed sensors to collect terminal information, their measurement accuracy and working stability are also greatly affected. In practical applications, electronic belt scales may experience inaccurate and unstable measurement accuracy.
Overall, electronic belt scales have advantages and disadvantages in measuring weight, with the main advantages being:
(1) It is convenient to achieve continuous weighing of bulk materials, with high weighing efficiency. During weighing, there can be a large adjustment range for the operating speed as needed, and there are no special requirements for the particle size and density of the material to be measured.
(2) When the quality distribution of the tested material is relatively uniform, the instantaneous mass flow rate can achieve high measurement accuracy. For the measurement accuracy of total mass, the uniformity of mass distribution during timely measurement is not high, but the final measurement errors cancel each other out in the cumulative process, and the measurement accuracy can still meet high requirements.
(3) With the application of computer information technology in electronic belt scales, software systems provide more data support for production management.
The main drawbacks of electronic belt scale measurement technology are:
(1) Due to different usage scenarios and requirements, the speed of the belt is not stable during operation due to various factors. Therefore, electronic belt scales should also provide accurate belt speed measurement.
(2) Due to factors such as belt tension and temperature, the measurement accuracy of the belt scale can be affected, increasing the relative error.
(3) When the material is applied to the belt, the dispersion range is relatively large with different conveying flow rates, and it varies with particle size, humidity, and belt speed, which also has a certain impact on measurement accuracy.
In the face of the main shortcomings of electronic belt scales, such as insufficient measurement accuracy or instability, Guonuo Technology mainly solves them through structure and technology:
(1) Customize different types according to the application environment to better adapt to the conveyor and environmental conditions. The scale frame has a sturdy load-bearing capacity and a simple structure.
(2) Utilize the built-in temperature sensor in the instrument to monitor the ambient temperature and incorporate it into the calculation, reducing the impact of ambient temperature on the measurement.
(3) Configure automatic belt tensioning and correction devices to avoid significant changes in belt tension or deviation.
(4) Change the structure of the speed sensor and the rubber coating design of the double wheel car to accurately reflect the belt speed.
(5) The sensor uses digital signals to improve anti-interference ability and reduce interference from electromagnetic and other factors on the signal.
In short, the application of electronic belt scales has its own advantages and disadvantages, with more advantages than disadvantages. To avoid the disadvantages in the application process, Guonuo Technology has been continuously innovating and solving them from the perspective of practical application, structure, and technology.
