Laser rangefinders are used to measure the length of lumber to ensure that the boards are cut to the correct length. While other methods of end-tallying lumber rely on human judgment or estimations, using laser measurement sensors guarantees that boards are measured and cut with extreme accuracy.
Continue readingLaser rangefinders can be mounted at the top of silos and aimed down at the surface to measure the fill level of the material in the silo. Due to the long operating range of the sensors, Acuity’s laser rangefinders are suitable for nearly any silo size.
Continue readingDuring the casting process, the AR700 laser is used to measure the surface location of the molten aluminum mold. In order to obtain a homogeneous oxide-free cast, the height of the mold must be precisely monitored.
Continue readingAcuity’s rangefinders are used at sawmills to measure the width of lumber boards while sorting on a conveyor line. A customer has an AR1000 laser distance sensor mounted in line with the board and housed under a higher conveyor area approximately 10 feet away.
Continue readingLaser sensors are commonly used in steel hot mills because they need an accurate, non-contact method of determining the position or dimensions of materials that are too hot to touch. Many of Acuity’s customers are OEM integrators who service the specialized needs of the Steel and Aluminum Mill customers.
Continue readingSawmills are harsh environments that demand accurate laser sensors under dusty conditions. Production of plywood and OSB (oriented strand board) sheet is highly automated. Several Acuity customers are system integrators who develop specialized instruments for the forest products industry.
Continue readingAs an ingot block gets squeezed down into a thinner and thinner sheet of aluminum, the operator needs to know the thickness of the sheet in order to be rolled to the correct size. Acuity has designed the AR700 for use on a mechanical caliper slide that positions two dual opposed lasers around the sheet
Continue readingAs metal moves over the top of the roller, the laser calculates the height of the metal to be used as the thickness of the metal. A single laser can be used for one point of measurement or multiple sensors across the roll for multiple thickness measurement points.
Continue readingThe thickness of polyethylene films may be measured in-line by using confocal displacement sensors. These ultra-precise sensors measure the thickness of thin, transparent sheet by simultaneously measuring both the top and bottom surfaces.
Continue readingThe thickness measurement of a plexiglass sheet is a very common application for laser displacement sensors. These product are often extruded between two polished rollers to squeeze the material into the desired thickness. This thickness must be measured and verified for in-process quality control.
