Description
1. Real – world Case
In a large – scale pulp and paper mill, the 3HNA024871 – 001 was integrated into the process control system for the paper – making machine. The paper – making process requires precise control of various parameters such as pulp consistency, speed of the paper web, and temperature in the drying section.
One day, during the production of high – grade paper, a sudden change in the pulp quality occurred due to a variation in the raw materials. The sensors connected to the 3HNA024871 – 001 detected the change in pulp consistency. The device quickly analyzed the data and adjusted the flow rate of the pulp and the dilution water. It also coordinated with the speed control of the paper – making machine to ensure that the paper web maintained the correct thickness and quality. As a result, the mill was able to continue production without significant quality issues, avoiding potential losses due to product rejection.
