The modular system, which also includes sensors and measuring frames, measures, records and controls critical parameters such as basis weight, moisture or layer thickness across the entire width of the fabric. Depending on the application and task, different measuring methods are used for this purpose. Among others, there is a choice of X-ray and beta radiation, white light interference or near-infrared measurement. The latter also uses the latest technical development from Mahlo: as the Infralot IMF-T version, the basis weight and moisture sensor also uses the transmission method for the first time when measuring. This makes it the ideal solution for thicker materials up to 500 g/m². In addition, in contrast to conventional methods, it completely dispenses with a rotating filter wheel. With Mahlo's newly developed simultaneous filter, all wavelengths are measured simultaneously and at the same point. Instead, the light is distributed simultaneously to six detectors. This eliminates measurement inaccuracies and enables true seed-spot measurement of reference and absorption resonances.
