Textile, dyeing and finishing industries have strict requirement against atmosphere humidity in environment. For example atmosphere humidity in the drying room in priming part of the dyer and in steamer after printing and dyeing is an important factor to affect quality of finished product. Meanwhile in course of production, atmosphere humidity in the drying room should be often regulated.The system can accurately make online detection upon atmosphere humidity in the drying room, and regulate control upon exhaustion fan or steam valve so as to reach the target to stabilize atmosphere humidity and save energy.
