COMPACT 2D/3D LASER SCANNERS WITH INTEGRAL CONTROLLERS REINVIGORATE PROFILE MEASUREMENTS
The integration of electronics inside a compact sensor housing simplifies the installation of 2D and 3D laser scanners – a major benefit in a wide range of applications in factory automation, robotics, machine-building and medical production, says Glenn Wedgbrow, Business Development Manager at Micro-Epsilon UK.
L
aser profile scanners — commonly comprised of a sensor, cable and controller — have
reached a new technology milestone: a compact scanning device with an integral controller for profile measurements with high precision. The integration of the controller part inside the sensor housing simplifies cabling arrangements and mechanical operations. More importantly, the integration of all of the electronics inside a compact sensor body makes the installation of 2D and 3D laser scanners much easier – a critical advantage in factory automation, medical production and machine-building applications where only a small installation space is provided. Laser scanners — also known as laser profile
sensors — detect, measure and evaluate profiles on various object surfaces with high precision. Their versatile tasks include measurement and
evaluation of angles, steps, distances, extreme values and more. Compact and lightweight sensors with built-in
controllers can better serve manufacturing and robotics applications where absolute precision is imperative in the measurements of tiny structures and small gaps.
WHY SIZE MATTERS IN LASER SCANNERS Traditional laser scanners that use external controllers carry both space and time overheads, a serious limitation when they operate on tight measuring locations. On the other hand, a compact sensor featuring integrated evaluations without an external controller or PC can be directly integrated to a PLC.
The new scanCONTROL 30xx laser scanners
from Micro-Epsilon offer the highest performance and are used for high-speed and precise 2D/3D measurement tasks. Equipped with an internal controller, the scanners can be easily integrated in various environments. Take, for example, multi-blade razor production
where all blades must be properly aligned, without any protruding. Here, measurement objects, in this case, blade points, offer a very small reference surface for angle measurements. The scanCONTROL profile sensor with a built-in controller and high point resolution in the x-axis can accurately measure the small reference surface of blade points during production control. Likewise, medical applications such as insulin
pens and pacemakers demand 100% reliable control, but their small housings make precision and detection extremely challenging for
