Diameter Measurement
Laser measurement sensors used for diameter measurement
The diameter of an object can be measured in different ways. A single point sensor can measure the diameter of an object if the center of the object is known. Two single point sensors can be used to measure the diameter if the center is unknown. 2D laser scanners offer a non-contact solution to create a profile of the object to accurately measure the diameter.
Acuity laser sensors can be used to measure both the inner (ID) and outer diameter (OD) of objects. Precise ID laser measurements are seen in many industries, especially the pipe industry. OEM companies use our laser displacement sensors as a tool to measure the inner diameter at short and long ranges, and inside tight areas. Manufacturing plants also use our laser sensors to monitor the diameter of coils, such as paper rolls and metal coils for inventory management purposes.
Non-contact laser measurements are well suited for diameter measurement because they can be installed at a safe distance far away from the coils, and provide accurate and fast measurements, without the drawbacks off touching the material. The laser sensors can be used on almost any target surface including hot metals. Accessories such as air and water cooled jackets are available with replaceable protective lens for hot targets.

Introducing Our New “Sessions” Feature on the Acuity Touch Panel Display
Our new Sessions allows the Touch Panel to detect when an object enters the sensor’s range and displays the average, maximum, minimum, and mode of the measurements after it passes by. As the name “Sessions” implies, this can be done with as many sequences as you need to get your highly accurate measurement.
Laser Scanning a Pipe for Diameter
Many manufacturing companies require an online method to measure their products as they are being made to a high tolerance. The manufacturing of pipe is an example of where a company can provide a superior product and automatically control the surface dimensions of their product to meet their specifications.
Measuring Diameter with the “Sessions” Feature on the Acuity Touch Panel Display
Last Updated: November 21, 2024 A very common application is measuring the diameter of an object. In this video, we show how to use the “Sessions” feature in the Acuity Touch Panel display to measure the diameter of a battery.
Metal Coil Diameter
Laser rangefinders can be mounted perpendicular to the coil surface. If the distance from the sensor to the roll core is known, a single laser rangefinder can be used to monitor the change in distance from the roll core to the sensor, giving way for diameter calculation measurements.
Paper Roll Diameter
As a very large roll of paper winds off to smaller individual rolls, manufacturers must ensure that the smaller rolls have enough material present to be able to sell.
Steel Tank’s End-Cap Dimensions
A manufacturer in Brazil designs and builds tanks and vessels for use in various chemical and petrochemical industries.The company approached Acuity to assist in improving their dimensional measurement practices.
