Nuclear? free QCS for Tissue Machines, TAPPICon22

Towel and Tissue paper companies now have an established alternative to the traditional radioactive basis weight sensors.  Since its introduction in 2008, infrared (IR) sensor measuring technology has been installed on over 300 of tissue/towel machines. Instead of having separate weight and moisture sensors, the single sensor is sensitive to both water and cellulose in tissue and can therefore accurately measure and control both weight and moisture.  This solution eliminates nuclear licensing requirements, reduces maintenance cost and possible failure points on the QCS. The IR technology also resolves numerous issues that can affect conventional nuclear measurement accuracy by having much lower noise, by being immune to temperature variation that have been known to disturb radioactive sources at standardize, and by reducing the impact of dust.  Because the sensor does not measure total mass, grade dependent calibration is used in cases where the machine has a wide range of furnishes and has varying amounts of fillers and/or lignin present.
