Optical thickness measurement in rolling mills
The new generation of thicknessCONTROL thickness gauges stands for exceptional performance and overcomes the challenges of one of the most difficult applications for optical thickness measurements. The systems are designed for use in hot rolling mills and are resistant to harsh environmental conditions. In different operating modes, these measuring systems provide results with the highest precision.
The systems are equipped with innovative Blue Laser sensors. The internationally patented measuring procedures for Blue Laser Technology allow precise measurements to be made on red-hot glowing objects above 700 °C.
The thicknessCONTROL mechanics are designed to partially compensate for changes induced by temperature gradients. In addition, a network of temperature sensors controls the state and stabilizes the measuring range using powerful signal processing. An additional, regulated cooling register and deflector plates even enable use in steel hot rolling mills at material temperatures of 1200 °C.
