Infrascope NIR
Measurement of basis weight (mass per unit area) / moisture
Absorption of infrared light
The Infrascope NIR monitors the absorption of infrared energy of all components on or in the web in the near infrared range. Measuring over the entire spectrum range and applying multivariate data analysis tools produces highly accurate calibration results from information in redundant spectra.
The Infrascope NIR is available in transmission and reflexion mode.
Product Highlights
- Non-nuclear
- Contactless, non-destructive
- Intelligent sensor with fast onboard micro processing
Customer benefits
- Non-destructive, continuous discrimination between multiple components
- High measuring accuracy
- Improved process understanding through online NIR spectral measurements
Contactless and continuous monitoring of all quality parameters with highest accuracy is extremely important for all web producing industries. The Infrascope NIR – Sensor can be widely used in pulp & paper manufacturing, the plastic film & extrusion industry as well as in the coating & converting sector.
Advantages
- By simultaneously analyzing the entire NIR Spectrum, the sensor is able to discriminate between multiple components in the web.
- Due to very high spectral resolution, the sensor can distinguish between components with nearly similar, but not identical, IR absorption.
- Improved process understanding by on-line NIR spectral measurements and use of multivariate calibration modeling.
- Reduction of waste and reworking through increased quality attribute measurements and optimized process control
NIR-T (Transmission): To measure the entire thickness of the product web
NIR-R (Reflection): To measure coatings
