Laser 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.
Continue readingThe metals fabrication business is one of the oldest industries in the world. Large mills are automated, but some smaller mills still rely on hand-held micrometers to gauge metal thickness. AR200 laser measurement sensors are ideal for measuring steel strip thickness to fine resolutions. Steel passes between two opposing non-contact laser sensors.
Continue readingA 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.
Continue readingThe forest, lumber and wood products industry is a regular user of Acuity laser sensor products for the measuring of logs, cants, lumber, veneer thickness, paperboard, etc.
Continue readingBefore material is cut into individual sheets, there can be a large sag created by the mismatch of speeds between two rollers. A global manufacturer sought to use laser distance sensors to improve the performance of their production lines.
