the continuous measurement of bulk solids on conveyor belts. Its frame-based construction allows for straightforward retrofit installation onto existing conveyor systems, making it particularly attractive for upgrades or plant optimisation projects without major mechanical modification. The WEIGHTRAC 31 operates using a radiation-based principle, enabling it to measure mass flow without physical contact with the material or conveyor. Because the measurement is non- contact, the system is largely unaffected by dust, dirt build-up, or material abrasion. This is a significant advantage in mining environments, where conventional systems can degrade quickly under harsh conditions. The WEIGHTRAC 31 provides accurate, repeatable throughput measurement even when belt loading is uneven or when vibration levels are high. Its wear-free operation also reduces the need for regular maintenance

81 provide a robust solution for continuous mass flow measurement in mining applications. The benefits to operators are significant. Reliable measurement is maintained despite vibration, belt tension changes, and harsh environmental conditions. Accurate throughput data enables precise accounting of bulk material flows between production units, supporting both operational transparency and financial control. At the same time, the system’s low-maintenance, wear-free design reduces lifecycle costs and simplifies long-term operation.

used in the measurement process. It ensures that radiation is emitted in a controlled and defined direction towards the measurement path, while effectively shielding the surrounding environment in all other directions. This design is critical for operational safety and regulatory compliance in industrial settings. The VEGASOURCE 81 is engineered for high operational reliability, featuring pneumatic actuation of the source holder for safe handling and control. Its compact design allows for simple installation even in constrained spaces, while its shielding efficiency helps minimise the need for extensive controlled areas around the installation. This makes it well suited for integration into existing conveyor systems where space and access may be limited.
Key technology advantage: Radiometric systems, like the WEIGHTRAC 31supported by VEGASOURCE 81, deliver continuous, maintenance-free mass flow measurement with high repeatability under unstable belt conditions.
