When looking for the best way to measure width, there are a number of important factors to consider, including the shape of the target, the type of measurement system, and the installation environment. Selecting equipment that doesn't adequately meet your needs can lead to insufficient precision and increased man-hours during production. This site is designed to help those looking for a width measurement system discover the best way to perform measurement with confidence.
Narrow targets can be measured using a single sensor head. For wide targets, use two sensor heads to detect the edge positions on the left and right of the target to measure the width.
KEY POINTS
It is possible to achieve higher precision measurements than with reflective measurement devices.
Even transparent targets can be measured stably.
Measurement of narrow targets
Example Application: Width measurement of elastomers
2D Cross-sectional area and width measurements can be easily performed.
KEY POINTS
The width of locations where laser light does not penetrate through can also be measured since the measurement system is a reflective model. The width of the specified location can be measured correctly even if the target shifts out of position to the left or right.
Measurement of wide targets
Example Application: Width measurement of building material boards
Width is measured by passing a target between two sensor heads.
KEY POINTS
The end face of the target must be an area wider than the measurement spot. Optical-axis alignment or span adjustment are important to ensure that A+B is fixed even if there is workpiece run-out to the left or right.
