Conveyor Belt Scales and Belt Weighers

WiseStone conveyor belt scales measure flow rate, belt load, belt speed and production total for mining, aggregate, cement, fertilizer, biomass, steel, recycling and bulk material handling conveyors.

Choose from dual, 4, 6, 8, 12 and 24 idler configurations to match your belt width, conveyor structure, capacity and target accuracy. Our engineers can help select the weigh frame, speed sensor, controller and calibration method for new conveyors or retrofit projects.

What Can This Belt Scale System Do?

Accuracy Options

Different weigh frame structures are available for process monitoring, inventory control, loading, unloading and higher accuracy production totalizing.

Calibration Support

Support for zero adjustment, dynamic test, recalibration tools and practical commissioning guidance for real site conditions.

Controller Display

Large color graphic display for flow rate, total weight, belt speed, belt load, alarms and daily production information.

PLC Communications

Ethernet supports Modbus/TCP, and RS-485 supports Modbus/RTU for PLC, SCADA and plant monitoring integration.

Multi-Idler Systems

From standard dual-idler scales to long weighing sections with multiple load cells for more stable and accurate weighing.

Wide Applications

Suitable for aggregate plants, quarry conveyors, mobile crushing lines, mining, cement, fertilizer, biomass, steel and recycling.

How to Choose a Conveyor Belt Scale

The best belt scale depends on belt width, belt speed, conveyor angle, idler spacing, material flow stability and the required weighing accuracy. A dual-idler belt scale is often used for general monitoring, while 4, 6, 8, 12 and 24 idler systems are selected for higher accuracy, heavy capacity or longer weighing sections.

Conveyor Belt Scale FAQ

What information is needed to choose a belt scale?

Please provide belt width, belt speed, conveyor angle, capacity, material, required accuracy, power supply, communication method and installation photos.

Which belt scale is suitable for aggregate conveyors?

Aggregate conveyors usually use dual-idler or 4-idler belt scales for production monitoring. Higher accuracy applications can use 6-idler, 8-idler or 12-idler systems.

Can the belt scale connect to a PLC or SCADA system?

Yes. The belt weighing controller can support Modbus/TCP through Ethernet and Modbus/RTU through RS-485 for plant integration.
