Product: Inline quality measurement system QUALISCAN QMS-12 by
Mahlo
Function:
Inline system for continuous measurement of thickness and basis weight
during production. Sensors are mounted on a traversing frame and move
left to right across the material to measure over the full production
width and length.
Measured parameters:
Thickness
Basis weight
Additional parameters possible depending on configuration
Measurement principles:
Thickness measurement by laser triangulation, double-sided measurement
of top and bottom surfaces
Measurement range: 0–100 mm
Reproducibility: ±25–50 µm
Basis weight measurement by X-ray transmission
X-ray intensity is reduced according to material mass
Reproducibility: 0.1 g/m² (1 sigma, 1 s)
Measurement gap: 60 mm
Water-cooled system
X-ray system details:
Industrial metal-ceramic X-ray tube
Variable power supply 15–50 kV
Special ionization chambers with noble gas filling
Compensation for temperature and product distance
X-ray radiation can be switched off
Sensor itself is not radioactive
Radiation only generated when voltage is applied
Safety information:
X-ray shutter opens only during measurement
Automatic shutter closing in case of power failure or malfunction
Clearly marked control and hazard areas
Visual status indicator with signal lights:
Red: shutter open, radiation emitted
Blue: tube active, shutter closed
Green: shutter closed, no radiation
Approach is safe when shutter is closed
System configuration:
Modular design, expandable with additional sensors and measuring
points
Continuous data acquisition for quality monitoring and automatic
control
Operating conditions:
Ambient temperature: 0–45 °C
Relative humidity: 0–95%, non-condensing
Power supply: 230 V 1~ or 400 V 3~, 50/60 Hz
Control and software:
19-inch color touchscreen operator panel
Real-time display of profiles, averages, min/max values, trends,
alarms
Recipe management and data backup functions
Interfaces for network integration and data logging
Traversing frame:
Sensors mounted on a traversing platform
Traversing speed: 30–300 mm/s
Aluminum construction
Integrated safety and position monitoring
Compressed air supported measurement gap stabilization
