Development Trends of Components in Electronic Belt Weighers

It is well-known that belt conveyors are automated mechanical equipment for transporting bulk solid materials. During their transportation process, electronic belt weighers can be utilized to achieve continuous cumulative automatic weighing of the conveyed materials.

With the advancement of industrialization, the volume of material transportation has increased, and electronic belt weighers have become indispensable in various stages of raw material procurement and production, highlighting their extensive usage.

Furthermore, with the implementation of energy conservation and consumption reduction strategies and the strengthening of refined enterprise management, accurate and reliable material weighing and metering have become even more crucial, underscoring the growing importance of the precision and reliability of belt weighers.

Since their inception, electronic belt weighers have evolved from mechanical to electronic, and now to intelligent-controlled types.

Mechanical belt weighers, which relied on lever force transmission and mechanical counters, had numerous shortcomings in terms of performance and accuracy and have largely been phased out. The development of electronic industries, along with the introduction and application of strain gauge load cells and microprocessors, has enhanced the measurement accuracy, performance, and reliability of electronic belt weighers.

Currently, electronic belt weighers have advanced to intelligent-controlled types. Although still classified as electronic belt weighers, they have significantly improved measurement system accuracy, reliability, and performance through technologies such as digitization, networking, and intelligence, as well as by altering design principles and concepts.

Moreover, through the interaction of measurement information, technologies such as real-time online testing, online calibration, and the integration of measurement and calibration have been realized, enhancing the durability of electronic belt weighers.

Trends in Weigh Frame Development

The structural evolution of electronic belt weigher frames has progressed from mechanical to lever-type, then to fully suspended, and finally to matrix combination types. This evolution follows trends of simplification, ease of operation, minimal force transmission, reduced friction, fewer mechanical components, and smaller horizontal surfaces.

For instance, the latest matrix combination weigh frame employs a fully suspended direct force transmission structure, where two rollers are equipped with four high-precision load cells as a single weighing unit module.

The entire electronic belt weigher measurement platform consists of multiple such independent weighing units. This structure offers benefits such as improved measurement accuracy and stability, as well as the flexibility to extend the effective weighing area by adding weighing units according to the conveyor's requirements.

Trends in Sensor Development

The development of sensors for electronic belt weighers is oriented towards higher precision, sensitivity, anti-interference capabilities, durability, wider applicability, and richer compensation functions.

For example, Guonuo Technology's digital high-precision sensors convert analog signals into digital signals and feature temperature and linearity compensation functions. Additionally, electronic belt weighers incorporate more sensors, such as position sensors to determine the relative position of the belt and temperature sensors to detect ambient temperature changes, thereby reducing the impact of adverse factors on belt weigher measurements.

Trends in Instrument Development

The instrument, serving as the data processing and computation core of electronic belt weighers, is developing towards intelligence, informatization, microcomputerization, simplicity of operation, and high performance.

For instance, Guonuo Technology's intelligent instruments feature intelligent online monitoring and diagnostic functions, enabling rapid fault detection, online zero-point calibration, and one-click calibration, thereby enhancing the overall stability and accuracy of the belt weigher. Furthermore, the instrument receives signals in real-time, processes them quickly, displays them promptly, and synchronously transmits data for remote viewing.

Trends in Calibration Technology Development

Calibration technology for electronic belt weighers is advancing towards self-calibration, online calibration, high precision, simplicity of operation, and calibration compensation.

This addresses previous issues such as difficulty in on-site physical calibration, delayed calibration, and complex calibration operations. Guonuo's belt weigher instruments feature real-time online zeroing and calibration functions, allowing for verification through methods such as chain codes, physical materials, and hanging codes, with high verification accuracy and simple operation, as well as remote calibration capabilities.

In summary, each component of the electronic belt weigher has its own development trends and directions. However, these components collectively drive the overall development trend of the electronic belt weigher measurement system, enabling higher precision, greater reliability and stability, enhanced durability, and wider adaptability.
