Width Measurement on Roller

3D Model

Width of a black material can be measured on the roller by installing the sensors as shown here. The first pixel of the sensors should be covered by the web and the last pixel should see the roller. The controller should be setup to be in contrast mode while the edge of the web on the roller can be selected by teaching for either the end of the dark web or the begining of the light roller. Both sensors would have the same orientation with the left part of the sensor being dark and the right part of the sensor being white.
