Basis weight measurement

Basis weight measurements are possible by non-contact measurement procedures as well as based on thermographic cameras or beta and classical x-ray sensors


The PC16S®-wave transmission sensor measures the surface weight or thickness of flat sheet materials, using non-ionising, electromagnetic waves for the contact-free measuring process. This is why it is perfectfor the accurate and rapid measurement of polymer-based mono films. Compared with sensors based on ionising radiation, the national or international official requirements inthis respect in terms of transport, operation and disposal do not apply to this sensor.

IndiRay® X Ray < 5kV / Extended Range

When the transmission method is used for basis weight measuring, emitter and detector are facing each other, with the measured material in between. Radiation is weakened by the measured object, and the degree of weakening is subject to the density, thickness and composition of the measured object.

IndiCam 100® / IndiTherm®

On the basis of measuring temperature with thermal imaging cameras (IndiTherm®), IndiCam 100® enables basis weight measurement and thickness measurement. The measuring principle analyzes the curve of temperature of materials at chill and heating rolls with highest precision.

Isotope Backscatter Sensor

Isotope transmission measurement is a contact-free measuring method, measuring the basis weigth (g/m2). It uses the fact that all radiation is decreased when passing through materials.

Isotope Transmission Sensor

The measurement by the isotope transmission sensors is a non-contact measuring procedure, which determines the basis weight (g/m2). This method takes advantage of the fact that radiation undergoes a decrease when it passes through materials.
