Optical measurement systems on strips – The VeriFlat – system
A strip is usually under tension; hence care has to be taken when measuring flatness optical measurement systems on strips. Tension “hides” flatness problems since the tension extends the shortest parts of the strip most. If the tension is too high, the strip will look totally flat, and contact-based methods must be used to measure the latent flatness. However, flatness can often be measured accurately in low-tension areas. In addition, crossbow is measurable also in high-tension areas, such as galvanization or hardening applications. Optical flatness measurement can also be useful in quench and temper lines for high yield strength or special steel.
VeriFlat is our most cost-effective solution for material up to 2 m width. A standard sensor, yet powerful for most applications in strip process and cut-to-length lines. Pre-calibrated and extremely easy to install.
