Precise Laser Measurements

Acuity laser sensors are used widely throughout the rubber manufacturing industry. Manufacturers demand our reliable, non-contact sensors to minimize downtime and scrap material production.

Laser Measurements on Difficult Target

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 sensor. Acuity can install an AR700 bringing 5 mW of laser power to get a stronger return signal off the dark surface.

Customer Example

A rubber manufacturer monitors the thickness measurements using four 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.
