The flatness measurement is based on the laser light-section process. It uses nokra sensors developed specifically for this application. These sensors are integrated into a gantry-type frame which moves down the complete length of the plate on high-precision rails.
The number and measuring range of the sensors are adapted to the customer's measuring accuracy requirements. The measuring range of the sensors assures that the system can provide the required measuring accuracy for the specified tolerances. To rule out any influence between adjacent sensors, the sensors are arranged with an offset of 150 mm.
When the sheet has reached the measuring position and is deposited safely on the gauging table, the gantry travels down the complete length of the plate scanning its height profile. The sensors in the gantry recognize the sheet end and automatically stop the measurement. After the gantry has travelled back to its starting position, the sheet is discharged from the gauging table.
