What is included in a belt scale?Composition|Working Principle

 Belt Weigher are widely using in electric power, coal, metallurgy, chemical industry, ports, building materials, etc.The electronic belt scale consists of five main components, including: Load Cells, Speed Sensor, Controller/Integrators, Idlers/Rollers, Weighbridge.

Definition of belt scale:

High precision matrix electronic belt scales are our response to the current measurement requirements of users who demand more and more precision, using multiple weighing units to form a weighing matrix to achieve very high weighing accuracy and operational stability. This characteristic high precision matrix electronic belt scale can measure the instantaneous flow and cumulative weight of the material passing through the belt conveyor without interrupting the material flow. It has unrivalled advantages in terms of principle and structure, technical performance, weighing accuracy and maintenance.

Features of belt weighing scales：

• Full English 7 inch touch screen full English operation, intuitive and convenient.
• Mechanical lock, password lock double protection.
• Intelligent detection function, can be used without opening and stopping the switch.
• Automatic report, support U disk export.
• A variety of structural methods: single-roller belt scale, double-roller belt scale, full suspension belt scale
• Support Modbus RTU communication, convenient for customers to network and remote operation.
• Customisable cloud data query function, to achieve computer, mobile phone remote login access, query and other functions.

Composition and function of the components of the belt scale:

• Load Cells
• Speed Sensor
• Controller/Integrators
• Idlers/Rollers
• Weighbridge

1、Load Cells for belt scales work:

Measure the force exerted by the material on the belt, converting it into an electrical signal for weight calculation.

2、Speed Sensor working principle for belt scales:

Monitors the conveyor belt speed, providing data for calculating material flow rate.

3、The Controller for belt scales works:

Processes data from load cells and speed sensors to calculate and display the material weight and flow rate.

4、The Rollers principle of operation for belt scales:

Support the belt and provide a stable surface for accurate weighing.

5、Weighbridge working principle for belt scales：

A supporting frame installed on the conveyor that holds the load cells and ensures accurate load transfer.

Belt scales are accurate with standard errors

After years of research on the factors affecting the belt scale: the force measurement error caused by changes in belt tension is the main source of error in the belt scale. In order to ensure the long-term stability of the belt scale, timely detection of changes in measurement accuracy, through real-time detection of changes in belt tension, the belt scale parameters for timely correction is particularly important.

Test demonstration, it is concluded that: tension optimised belt scale long-term measurement accuracy is better than 0.1%.

Why choose belt scales from KNKT？

KNKT is the main drafter of the national standard for electronic belt scales. Electronic belt scales have a high share in the domestic market for fifteen consecutive years. From the field of physical calibration technology of belt scales, the company has created the ‘material superposition self-calibration technology’, which realises real-time on-line monitoring and calibration of belt scales using a small amount of material; in the reliability of belt scales, the company has created the ‘three cumulative quantities and automatic identification technology’ to solve the world’s problem that the belt scales can still be measured even if the sensor fails.

In order to improve the accuracy of belt scales, the company has created the ‘free floating technology’. In terms of the reliability of belt scales, the company has created the ‘three-group cumulative quantity and automatic identification technology’, which solves the world problem that belt scales can still be measured even if the weighing sensors are faulty; in order to improve the accuracy of belt scales, the company has created the ‘free-floating balanced weighing structure’, which solves the problem of high-precision measurement of belt scales. Users involved in coal, electric power, iron and steel, cement, ports, chemical, food and other industries, products throughout Asia, more than 10,000 sets of products in reliable and stable operation.
