Length Measurement

Aluminum is often sold in long sheets, sometimes up to 20-30 feet long. The customer expects these sheets to be a specific length.

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.

Acuity helped a copper bar manufacturer identify both a non-contact solution and formalize their upgrade investment justification.

An overview of common challenges, best practices, and tips to help make fiberglass cut-to-length and thickness measurement systems successful.

A large steel producer makes products in various shapes and sizes. Laser sensors measure the position of the end relative to the distance to a saw blade.

When drilling down for oil and gas, the drill tower and drill are attached to a piece of pipe. One customer has used the internal module of the AR2500 laser sensor to notify workers to attach the next pipe to continue to drill deeper into the ground.

Rangefinders are used in the manufacturing process to make sure glowing yellow/red hot billet lengths are to the correct length dimensions. Laser rangefinders can be remotely installed and offer a safer solution.

A system integrator in Croatia worked closely with a steel pipe manufacturer to develop a system for measuring the length during production. The clever solution incorporates an AR1000 laser distance sensor from Acuity to measure to the leading edge of the pipe during cutting.

Lumber mills are taking advantage of the high speed and high accuracy AR2000 sensor for sorting applications. As lumber is moved down the conveyor line, sensor length measurements are made on each board in less than two seconds.

The dimensional measurement of pipes is crucial for manufacturing to strict tolerances. A system integrator uses a pair of AR1000 laser distance sensors to measure the differential length of hollow pipe during its production.

Our 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.
