The 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.
Continue readingA maker of foundation pile testing equipment uses laser rangefinders to collect set data, acquiring it much faster than hammer impacts. The rangefinder is affixed to a stationary base. The automated equipment is set up prior to starting of the hammer and does not require the use of manual recording methods.
Continue readingA major audio speaker manufacturer contacted Acuity to help solve a challenging applied measurement problem. In this sound vibrations scenario, a sensor with fast frequency response was needed to profile the entire amplitude of cone movement.
Continue readingOur customer from the lumber industry is using the AR2000 laser sensor to measure the length of cut lumber as it moves down the mill. With a measurement range of over 300 feet on natural targets and an accuracy of 0.040″ at 20 Hz, the AR2000 is a good fit for this customer.
Continue readingFor distance measurements on hot surfaces or in bright lighting conditions, the Acuity AS2100 series is superior to previous Time-of-Flight lasers.
