A mine's belt scale error dropped from 2% to 0.5%
A limestone mine in Guizhou used to have a 2% dynamic error on their belt weigher. That caused short shipments and many customer complaints. We replaced it with a full-floating belt weigher with dual levers and a speed sensor. After calibration, the dynamic cumulative error stabilized at ±0.5%. No more short shipments. The mine manager said: "Finally, we don't lose money on deliveries."

Remote calibration without test weights
The integrator has auto-zero and auto-span functions. You can operate them via RS485/Ethernet remotely. This reduces on-site calibration time. We also offer a test weight or chain code calibration device. You can check accuracy without using real material. The belt weigher data can connect to your DCS or ERP. It automatically generates production reports and helps with material balance. For long conveyors, we offer dual-channel or multi-channel integrators to measure flow at multiple points. A common question: "Can your belt weigher handle sticky material?" Yes, but cleaning may be needed. Yixing Silvanus Electric Manufacture Co., Ltd. has been making belt scales since 2007. Choosing us turns your conveyor line into a precise flow meter.
