Profilometers provide high-quality measurements of pavement deformations at highway speeds. The equipment measures the longitudinal and transverse road profiles, International Roughness Index (IRI), wheel path rut depth, Ride Number (RN) and macro texture of asphalt and concrete surfaces.
Continue readingThe leading electric motor and generator servicing company in the US uses four laser measurement sensors to measure the amplitude of vibration of large diesel generators. Their test setup has the sensors measuring the displacement of the diesel engine (generator) support rails while the system is idling and during heavy loading.

The automated process uses several pneumatic cylinders to put the molds into a properly “stacked” position. It is imperative that these molds are properly positioned so the front and back sides are aligned.

Continue readingA global manufacturer of self-contained drill rigs uses the AccuRange 1000 laser distance sensor to automatically gage the depth of drilled holes. Their drill rigs are equipped with powerful down-the-hole hammers for high-capacity rock drilling in quarries, opencast mines and construction projects. The operator, sitting in a climate-controlled cabin, can know the exact hole depth on a digital console display.

Continue readingIn this application, engineers tested the Acuity AP620-7 laser line sensor to make dimensional profiles of a small polymer part used in an industrial applications. Currently, the company uses calipers and comparators to measure this part. The area to be measured is a diameter at the circumferential “shoulder” formed by the floor of the part and an interior wall. Proper detection of the joint between the 30° wall and the horizontal surface was very important. Additionally, it was critical to align the laser line with the diameter of the circular part and not a chord. Any misalignment would result in a shorter diameter measurement. Engineers suggested scanning the part as it passed beneath the scan line and then capturing several cross-sectional frames. Software algorithms could be used to determine the maximum dimension of all collected and this number would be the diameter.
