Belt scales are automatic weighing devices installed in belt conveyor systems. They are capable of not only detecting the weight of bulk materials conveyed by the belt at a specific instant but also calculating the total weight of materials transported over a certain period.
Belt scales are widely used in industries such as mining, ports, building materials, chemicals, and cement for weighing bulk materials. Electronic belt scales integrate advanced technologies such as mechanics, electronics, and sensor technology.
As a contact-type dynamic measuring instrument, they employ weighing sensors to detect the weight information of bulk materials passing on the conveyor belt, speed sensors to measure belt speed signals, and microcomputer intelligent instruments to process and compute the final weight information.
With technological advancements, the functions and performance of electronic belt scales have been significantly improved and upgraded, resulting in simpler structures, greater practicality, enhanced performance, and richer features. Their applications have become increasingly widespread, providing more support for fine enterprise management on the basis of accurate dynamic weighing.
Electronic belt scales find applications in almost all scenarios where belt conveyors are used to transport bulk materials. By incorporating PLC technology, electronic belt scales can achieve quantitative control and are utilized in blending systems for ironmaking plants, food processing, and chemical industries.
In wood chip conveyor systems for pulp and paper manufacturing, the usage statistics of wood chips primarily rely on the measurement data from electronic belt scales.
Accurate data for internal settlements within enterprises and trade settlements at ports and terminals are based on the statistical measurements provided by electronic belt scales.
Electronic belt scales are used to measure the coal input to boilers in thermal power plants, serving as a crucial basis for internal accounting and statistical coal consumption.
Real-time and accurate monitoring of coal production in coal enterprises is necessary to prevent overproduction, and electronic belt scales automatically, accurately, and in real-time measure and transmit data on raw coal, providing original and accurate data for coal production monitoring.
During their application, electronic belt scales offer various functions:
(1) Dynamic Measurement Function: Electronic belt scales possess functions such as instantaneous flow rate calculation of materials on the conveyor belt, flow accumulation, automatic zeroing, and automatic zero tracking. These functions provide users with accurate instantaneous material flow rates and weights over specific periods, serving as a basis for production management. Automatic zeroing and zero tracking ensure more stable and accurate measurements by the belt scale.
(2) Monitoring Function: Modern electronic belt scale instruments feature microcomputer and intelligent characteristics, including status prompts, process alarms, and monitoring functions for setting errors and equipment failures. When issues such as overloading, high/low flow rates, belt slippage, overspeed, or equipment failures occur during the measurement process, the instrument automatically alerts and records the monitoring information.
(3) Printing Function: The instrument is equipped with a serial interface that can be connected to a printer for printing, and it supports remote printing capabilities.
(4) Communication Function: The instrument offers a rich variety of communication interfaces and supports multiple communication protocols and standards, which can be configured according to requirements. The communication function enables the belt scale to be integrated into information networks, facilitating data sharing. Leaders can view real-time/historical measurement data and equipment operation status through the belt scale's upper computer software system.
Through the various functions and more stable performance of electronic belt scales, they provide accurate dynamic measurements while offering more support for users' production management and monitoring, thereby promoting the realization of fine enterprise management.
