Rubber Sheet Thickness Measuring with Laser Sensors
During calendaring and rubber processing, the surface of the rubber sheet is very shiny and very black, creating conditions where little light can be reflected. These are often the most challenging conditions for optical measurement sensors attempting to gauge rubber thickness measurement. Acuity can install an AR700 laser displacement sensor, bringing 5 mW of laser power to get a stronger return signal off the dark surface.
In one common scenario, a rubber manufacturer monitors their thickness measurements using four displacement sensors positioned at the top, 140 mm (5.5 in.) from the sheet surface. The rubber sheet lays across a roll cylinder. The top of the roller is the reference (zero) surface for thickness measurements. The laser spots aim directly perpendicular to the sheet surface at four different points across the sheet width for this process where the material stretches between two rollers, so that the roller gap can be adjusted accordingly to produce the desired (consistent) sheet thickness.
