Fiber optic based NIP pressure monitoring system

The exact processes in a ‘nip’ cannot be detected when a paper machine is running and until now could not be measured. These processes are extremely important for producing high-quality paper and this is exactly where NipVision™ comes in.

Figure: Fiber optic sensors embedded within the roll covering, measures the force exerted by the two rolls on the paper.

DTG®s embedded in roll covers make the invisible visible for the very first time and thus measurable as well.  Continuous data is transmitted wirelessly to a computer, monitoring not only the nip pressure but also the effect of machine setting changes, as well as the condition of the roll cover itself.
