Sensors

The right tool for every application

The Qualiscan QMS is a modular system consisting of multiple measuring sensors and measurement frames acting as intelligent nodes on a network. Some frames can run up to five Mahlo sensors at once, continuously, precisely and rapidly across the online product.

The versatile sensors and measuring devices of the Qualiscan QMS series can sense, log and continuously control such parameters as weight per unit area (basis weight), coating weight, thickness and moisture in a variety of web-type products.

Scanners

Universal application

The measuring frame traverses the sensors on-line across the whole product width and provides a cross-machine direction profile of basis weight, thickness or moisture on the display console that is a crosssection of the manufactured product.

One or more different measuring frames can be connected to a Qualiscan QMS system. Connection is made via a normal network cable, a standard 230/115 V source supplies the power.
