AR4000-LIR laser rangefinders from Acuity, USA are being successfully used in the forest products manufacturing industry.
The laser rangefinders accurately measure the distance to cut logs, lumber and can even gauge the thickness of wood veneer.
The rangefinder can measures the distance to the butt ends of cut logs as they travel down the log ladder.
The customer can use the 4-20 mA current loop output from the laser rangefinder for his PLC to determine the log length and position as it proceeds to sawmill applications.
The laser displacement sensor has the ability to measure large distances to over 15m to difficult targets and it can repeatedly do so in harsh environments. It uses an infrared 780 nm 8 mW laser.
The laser scanner sweeps a laser spot through a 360° rotation for the measurement of profiles and scenes. The line scanner is often further integrated to create 3D laser scanners.
The AR4000-LIR laser rangefinder is available from Bestech Australia.
