Strip Width Gauge WGL1000

Strip Width Gauge  WGL1000


2 Light Source Image Management

  • Reduce variation (error) due to changes in strip pass line
  • Sensor unit for detection with self-check function

Installation above the strip

  • Flexible installation (all installation above strip)
  • Easy maintenance due to accessibility
  • Reduce adhesion of dirt in LED and sensor unit


The system consists of LED light source for illumination, Sensor unit for detection of the strip and a specialize control panel with image processing unit for data analysis and I/O management. The sensor unit is connected to the specialize control panel using general purpose device net cable and LAN cable.

The system uses the laser triangulation method wherein it uses a capture camera image of projected line laser to detect the edge position and surface profile of the strip. This data is then translated into spatial axis (X,Z) using predetermined parameters. The measurement data for strip width and deviation can then be outputted to a level 2 computer.
