Matrix-Type High-Precision Belt Scale Achieves Trade-Grade Measurement Accuracy

Belt scales measure the weight of materials while they are being conveyed, offering advantages such as low cost and high efficiency.

They are particularly important in industrial settings for the measurement of bulk materials where static weighing is inconvenient. However, in industrial environments, ensuring the accuracy and long-term stability of belt scales has been challenging, limiting their use in high-precision measurement scenarios such as trade.

Nevertheless, with advancements in belt scale measurement technology, sensor technology, and design concepts, the matrix-type high-precision belt scale has effectively addressed issues such as insufficient accuracy, poor long-term stability, difficult manufacturing, installation, and debugging, as well as complex operation and application. It has quickly become a favorite in the industrial automation measurement industry, capable of meeting trade-grade high-precision measurement requirements.

Designing a New Structure Supported by New Theories

The variation in belt tension of belt conveyors has always been a significant factor affecting the accuracy and stability of belt scales, and it is unavoidable. The matrix-type high-precision belt scale is designed based on the "internal force theory," featuring a suspended, beam-free, matrix-arranged scale frame structure. In a continuously installed belt matrix, each weighing unit interacts under the influence of belt tension.

By intervening in calculations according to a specific mathematical model, the mutual influences among the weighing units can be eliminated, while the impact of belt tension is limited to the entry and exit units of the matrix. Furthermore, by analyzing the weight data from each weighing unit in the matrix, the influence of belt tension can be quantified and corrected using the "compensation theory."

This minimalist matrix-type scale frame structure fundamentally eliminates the influence of belt tension. By removing bulky mechanical components, it reduces self-weight and enables installation without the need for additional auxiliary mechanical devices.

The minimalist structure also prevents material from getting stuck and reduces dust accumulation, eliminating the need for daily maintenance and ensuring long-term stable operation. By addressing various influencing factors, the ultimate result is a significantly improved measurement accuracy, which can be maintained at a stable level of 0.2% over the long term.

Creating New Components Based on New Technologies

The matrix-type high-precision belt scale employs advanced electronics, microcomputers, and intelligent technologies to create a new multifunctional intelligent control instrument. It utilizes multiple high-performance microprocessors, offering comprehensive upgrades in data acquisition, processing, display, expandability, human-machine interaction, networking, and intelligent functions.

The instrument optimizes the weighing sampling circuit and speed measurement circuit to enhance data acquisition accuracy. It extends communication and control structures that comply with industry standards, facilitating easy network integration.

By applying intelligent technologies, the instrument enriches its functions, such as online zeroing calibration, one-click calibration, online fault monitoring, and intelligent identification and diagnosis, with high accuracy and real-time fault identification, further improving the measurement accuracy and long-term stability of the high-precision belt scale.

Additionally, new sensor technologies are used to create high-precision cantilever beam digital weighing sensors equipped with digital-to-analog converters.

These sensors offer strong filtering capabilities, release digital load signals, extend signal transmission distances, and enhance anti-interference capabilities during signal transmission. They also feature diverse compensation functions.

Manufacturing New Hardware According to New Standards

The matrix-type high-precision belt scale adopts high-precision manufacturing techniques and is manufactured and inspected in strict accordance with new industry standards, providing a reliable hardware foundation for its high-precision and stable measurement applications.

Since its introduction into practical applications, the matrix-type high-precision belt scale has received high recognition and praise from users for its excellent measurement accuracy, stability, and operability. It meets the requirements of all high-precision measurement scenarios, including trade settlement and production monitoring.
