Bestech Australia presents the thicknessCONTROL MTS 8201.LLT O-frame measurement system from Micro Epsilon designed to measure material with large widths up to 4000mm at a precise accuracy from ±5µm.
Equipped with laser line scanners to determine the thickness profile of individual metal strips in slitting lines, the Micro Epsilon MTS 8201.LLT is used in thickness profile measurement applications in process and quality control as well as metal inspection in rolling mills and service centres.
Application fields in metal mills include hot and cold rolling, splitting lines, coating, drawing lines, cutting, channelled sheets (base plate thickness and channel heights), and ‘sandwich plates’ made from non-homogeneous materials.
The laser line sensor ensures a material-independent measurement and higher precision. In a slitting line, the thickness of metal strip can be measured prior to or after the slitting operation.
Metal strip thickness measurements are continuous and non-contact while the strip profiles are measured before the slitting shears due to space constraints. The visualization software splits the entire captured cross-section into individual strips. Traversing thickness measurements cover strip widths of up to 4 metres perpendicular to the material flow.
The thickness profiles of the slit strips are determined and individually documented for each sheet ring, which allows the longitudinal position of any detected tolerance deviation to be known for each strip. Seamless quality documentation enables the selection of products by order and customer, leading to a predictable ROI. To save space, the measurement system can also be mounted before the slitting shears, making it possible to associate the measurements with the resulting strips at different widths. All measurements are carried out inline during the production process.
In addition to the fully-automatic calibration, the systems optionally dispose of temperature-invariant compensation frames, which ensure that the measurement is not affected by temperature influences, making them suitable for applications in harsh industrial environments.
The MTS 8201.T uses laser triangulation, MTS 8201.C adopts capacitive sensing, MTS8202.E uses eddy current sensor and MTS 8202.LLT employs CFK C-clap systems for measurements.
