Heavy plate steel

In rolling mills for heavy plate, the remarkable ratio between measuring range and precision comes into effect, which is achieved by using discrete laser line technology and by embedding a best-fit line into the point cloud of the sensors, which increases the resolution significantly. High linearity is achieved due to efficient signal processing.

Special features:

  • Geometrical measurements based on radioactive radiation
  • Cost-effective service-lifecycle-management
  • Iterative calibration compensation for thermal effects
  • Large measuring range with high precision
  • Mechanism protects lenses from dirt
  • Comprehensive analysis software with numerous graphs for cross-sections, longitudinal profiles, SPC analysis and false-colour representation

System type:

C-frame thicknessCONTROL MTS 8202.LLT


C-frame after trimming process for thickness control purposes

Thickness measurement system as a C-frame with laser line sensors

The MTS 8202.LLT is equipped with laser triangulation scanners which means measurements are independent of the surface properties of the target material. Scaling or mirror effects of the metal surface are therefore absorbed. Furthermore, compared to point sensors, the system offers higher accuracy and a larger mouth width. Automatic inline calibration ensures that measurements are unaffected by temperature changes. The measurement line is arranged vertically to the material flow, enabling the system to cope with lateral strip tilting.

Special features:

  •     Linearity of ±5 µm with measuring range of 40mm
  •     Mouth width 300mm
  •     Immersion depth 50mm to 800mm
  •     Special sizes on request
  •     Measuring rate up to 2kHz
