Belt Scales with SysTec Weighing Indicators at Limestone Plant
Carrières de la Vallée Heureuse uses SysTec IT2000M weighing indicators for its conveyor belt scales.
In limestone quarry operations, reliable throughput measurement is essential for production control, stock management, performance monitoring, and equipment protection. For Carrières de la Vallée Heureuse (CVH), a French limestone quarry, enhancing two main conveyor belts with modern weighing technology was an important step towards greater process transparency and production control.
The French SysTec partner Opale Pesage implemented a high-precision conveyor belt scale solution at the CVH quarry using SysTec IT2000M weighing indicators.
The Process
After the limestone is crushed, the material is transported to the processing plant. On the conveyor belt, the SysTec IT2000M weighing indicator continuously measures the belt load via load cells. At the same time, the current belt speed is determined via an optional encoder input (OP-ROT from Opale Pesage).
Based on these values, the SysTec IT2000M weighing indicator calculates the current throughput in tonnes per hour as well as the continuously accumulated total quantity. The material flow (feed rate) is transmitted via the analog output.
Additional scale data, such as scale status and further diagnostic information, can optionally be transmitted via fieldbus communication in future.
The use of the SysTec IT2000M BELT provides several advantages within the weighing process. The precise measurement data can be made available via the Modbus interface in the future, enabling accurate control of crushers and screening systems in line with the actual conveying capacity and helping to prevent bottlenecks or overload situations. Continuous data availability supports real-time comparisons between the target and actual values, and provides a reliable basis for planning and billing processes.
The SysTec weighing indicator IT2000M with stainless steel housing features a DIN rail design intended for installation in a control cabinet, ensuring reliable operation in harsh industrial environments. It can be used as a stand-alone system or integrated with a PLC. It offers versatile connectivity for digital inputs and outputs as well as fieldbus systems, and includes internal counters for throughput, shift totals, and overall totals. An integrated operator interface allows local monitoring and calibration within a compact control cabinet.
Overall, the integration of the SysTec weighing indicator IT2000M into the belt scale system represents more than just a measuring device; it forms an integral part of the process chain in the limestone plant. It enables precise acquisition and transmission of weight data, optimizes production processes, and supports the economic management of the entire material flow—demonstrating how modern weighing technology contributes to efficiency in the raw materials industry.
