The selection of electronic belt weigher should follow the small knitting of the belt weigher manufacturer.
1. Indication method of electronic belt scale model
According to the national standard Electronic Belt Scale (GB/T7721-2005), the model of electronic belt scale is shown as ICS-800-4T (800 is the belt width, 4T is the number of idlers);
2. Type of accuracy grade of electronic belt weigher
The electronic belt weigher is an automatic weighing instrument, and its accuracy grade is different from that of the static weighing instrument. According to the national standard Electronic Belt Weigher (GB/T7721-2005), the accuracy of the electronic belt weigher is divided into four grades, with the symbols of (0.25), (0.5), (1.0) and (2.0).
3. Purpose of equipment selection
First of all, it is necessary to find out where the equipment to be purchased is used, whether it is used for commercial trade settlement or internal accounting. If it is used for commercial trade settlement, equipment with high accuracy should be selected, such as (0.25) and (05). If it is used for enterprise internal accounting, electronic belt weighers of (05), (1.0) or (2.0) can be selected. Because of the high accuracy of electronic belt weighers, not only the initial investment is large, but also the maintenance workload and maintenance costs are large. It is also necessary to select higher calibration and installation, such as physical calibration and installation, Its investment is nearly 2-3 million yuan. Some users are prone to misunderstandings. Before ordering, they choose high-precision belt weighers without analysis. Just imagine that the reason is the same as the selection of (II), (III) and (IIII) scales in the static scales. The difference is that the calibration and installation of the equipment are provided by the user, while the static scales are handled by the consumer manufacturers.
4. Configuration of the selected device
After understanding the purpose of purchasing equipment, it should be made clear whether the purchased equipment needs to add other functions, so as to select relevant configurations. Then it should submit a request to the manufacturer for selecting equipment, including the basic configuration of the equipment (body, computer integrator, etc.) and the selected configuration (communication board, print board, analog current interface board, remote display, etc.). Among them, the model and price of the central component computer integrator vary greatly. At present, Xuzhou 10-201, American MT2000 series, Japanese CFC-100 series and German 400 series are widely used in China. Because the configuration price is expensive, users should properly stop selecting according to their own needs, such as the optional printer for commercial trade and remote counter for internal accounting.
