I need recommendations for a sheet edge sensor for roofing manufacturer. We are currently using 2 contrast sensing photo eyes and because of sand, slate fumes and steam we need to find a more reliable solution. the fiberglass sheet is just exiting the asphalt coater so it is quite hot (350F) and I want to go to a thermal sensor as it would not see the dirt as readily. Does anyone have any experience sensing sheet edge this way? I will be against a water cooled drum and the output will be controlling 3 Yaskawa servos that can be programmed for either digital or analog control.
