How to apply temperature and humidity sensors in the paper industry

Why is it necessary to monitor temperature and humidity in the paper production process?

  First, because the main component of paper is plant fiber, it is a material that is easy to absorb moisture. Temperature and humidity are very likely to cause loss of paper size and substrate platform degree. Second, when paper is stored in a humid environment, it will absorb moisture from the environment and increase its length, which will directly lead to unevenness and ripples. Third, paper in too dry environment will lead to the release of moisture from the edge to the center, will form the phenomenon of edge up curling, but also affect its mechanical properties. Fourth, it seems that the temperature does not have a significant impact on the drying process, in fact, it is not, because even if the air has absolutely the same vapor content, the relative humidity with the temperature changes produce large deviations in the data, in the winter, even if the outside air is very humid, once heated to a comfortable level, its relative humidity will drop dramatically. For example, saturated air at 0°C, when heated to 23°C, has a relative humidity of less than 22%. This shows the importance of temperature and humidity on the paper making process. The optimal temperature for paper production is 23°C ± 1°C and the humidity is 50% RH ± 2%. The use of temperature and humidity sensors for real-time monitoring is very necessary. Temperature and humidity sensors are characterized by high accuracy, small temperature drift, fast measurement response and good long-term stability.
