QCS stands for Quality Control System, a core online monitoring and control device for paper machines. It continuously measures critical paper parameters such as moisture content, basis weight and caliper via integrated sensors. The system feeds real-time data back to the control unit for dynamic adjustments. It effectively maintains uniform paper quality, lowers defective rates and operating costs, and has become an indispensable part of automated paper production lines worldwide.

1. Dynamic detection accuracy assessment method: Fix a piece of paper in the scanning frame, run the probe from the left limit to the right limit, calculate the average value, repeat 20 times, and calculate 2σ for the 20 gathered data sets.
2. Control accuracy test: Take several rolls of paper and sample each roll of paper (generally 20) banner quantity and moisture average for 2σ calculation.
