Width Measurement
Laser Sensors Used for Width Measurement

Width measurement of an object is an important part of dimensional control. Often called thickness measurement, it is often used to monitor the dimensions of products of assembly lines such as strip/slab metal thickness. If two sensors are used for width measurement, when material passes in between two sensors, the devices measure the distance to the edges and calculate the material width.
When selecting a sensor for width measurement, it is important to consider the shape of the target, target speed, and type of measurement needed (range, speed). Acuity laser sensors offer non-contact options for nearly any width measurement application. Our 2D laser sensors are typically used in width measurements to control for target position and edge control. Our laser displacement sensors are typically used in quality control processes to ensure correct packaging and dimensional control measurement of different materials.
The advantages of using non-contact laser sensors are to allow for precise and accurate measurement without the drawbacks of contact measurement. This allows for precise width measurement of nearly all materials, even materials with very soft surfaces.
Dimensional Measurement of Airline Cargo
Whether you need to measure small cargo before packing it into a Unit Load Device (ULD), or make sure large cargo can fit through the plane’s cargo door, our AS1100 Long Distance Sensor can give you the information you need to load your cargo efficiently and safely.
Hot Steel Slab Width
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.
Lumber Board Width Measurement
Acuity’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.
Steel Plate Width and Edge Control
One of Acuity’s customers is a large sheet metal fabricator and is using the AP820-1000 blue laser line sensor to control the position of the steel plate in the slitter line.
Width and Gap Measurement
A customer has an application where they needed to be able to measure the width of a woven material very accurately as it is being made. The customer decided to use the Acuity AP820-80 laser line sensor that projects a laser line of 580 points across a laser line of a 2.5″ length.
