Width Gauge

Width measurement on hot and cold metals

The Stereoscopic Width Gauge is a precision measurement device used to determine the width of sheet or strip products during rolling. This unit is a vision-based, noncontact measurement system, capable of providing real-time width measurements with typical accuracy of within +/- 0.5 mm of the effective width. The Width Gauge determines width by imaging the edges of the strip within the focal depth of the system. The stereoscopic design feature allows for accurate width measurement even if the strip is moving up or down within the measurement area.
When combined with Vision System Software, a significant increase in Yield can be achieved in a very short time.

The width gauge can:

  • Generate views of physical and thermal gradients
  • Calculate operational parameters such as deviation from center, overall width, camber, hook, etc.
  • Raise an alarm in case of excessive conditions, such as excessive hook



The width gauge can be cobined and integrated to advanced vision system software to obtain an extremely efficient optimization:
feedback can be used by the Vision System to compare the ideal, optimum cut point with the actual cut point as reported by the Shear.
These values can be used to calculate the ideal weight of the Cropped Head or Tail and the actual weight. All of the calculations can be organized and displayed on Crop Loss Report.

  • Technology:Artificial Vision
  • Measurement:Hot slab / plate shape and thermal map
  • Architecture:PLC based + PC as HMI
  • Software:Dynamic sub-pixel interpolation

We are specialists in process optimization. As manufacturer of industrial measurement and control systems for steel mill applications throughout the world we've collected a large number of experiences in the hot metals making activities. We have been successful providing solutions to rolling mill customers for 20+ years. In our group, many of our staff members have 30 - 40 years of experience in this industry.

Width gauge will determine the width of the measured part. Together with the Crop Optimization software and Shear Control System it will reduce/manage the Crop Loss.
