Paper Mill Hood Measuring humidity of air exiting from the hood In paper manufacturing it is important to control the moisture content in the paper to an optimal level based on the end-use e.g. printing. Typically the paper mass is not measured directly, but paper mills use the hood air measurement to monitor and control the drying process indirectly, and for avoiding excess humidity in the hood. This measurement is especially demanding if there is a risk of condensation combined with elevated temperatures. Vaisala provides fixed humidity transmitters for different dryer types, and also hand-held meters for spot-checking and verifying the operation of the fixed instruments.
