OnV FeltView is a system for continuous online measurement of felt moisture and permeability for the clothing in the press, enabling optimized felt conditioning.
The measuring head is equipped with two sensors. A moisture sensor based on microwave technology determines the felt moisture on the basis of the change in the dielectric constant. This change is brought about by the quantity of water present in the felt. A permeability sensor measures the pressure difference between a water jet penetrating the felt and a reference pressure, thereby determining the permeability. The machine speed has no influence on the measurement process. With OnV FeltView, felt conditioning is optimized, energy is saved, and felt wear is reduced.
OnV FeltView is used in the press section, and it was recently optimized for the special requirements of hygienic paper production.
