Laser measurement

Wednesday, 22 August, 2007 | Supplied by: SICK Pty Ltd


The LD-LRS laser measurement system is a powerful outdoor system for non-contact three-dimensional distance detection. The long scanning range of the long-range laser scanner, combined with its swivelling on the mounting platform, allows natural surfaces to be detected at distances of up to 250 m, and conversion of the measurement data to a 3D surface profile.

Typical applications of LD-LRS 3D include detecting filling levels in coal, waste and other bulk material bunkers, determining the profiles of heaps of materials for feed and removal systems.

It consists of an LRS long-range laser scanner with a scanning angle of 300° mounted on a platform, and a servo drive that turns the platform through up to 135°. Constant swivelling at a speed of up to 100° per second is possible, as is the triggered movement of the platform to defined positions. A 3D image of the surroundings can be generated by linking the 2D laser scanner data with the encoder value for the current angle of rotation of the platform.

Attention was paid to ensure an appropriately robust housing - because the typical areas of use are outdoors. The servo drive, encapsulated in a separate box, has an enclosure rating of IP66, while the heatable laser scanner is protected against the ingress of dampness and solid materials with a rating of IP67. Immunity to impacts and vibrations complies with IEC 68.
