Log Height for Inventory Control Posted in: Height Measurement – Tags:

Measuring height can be a highly affordable method for inventory control. At lumber mills, bridge cranes are used to transport logs to different locations throughout the mill. Acuity’s long distance sensors can be mounted on the cranes to profile the height of the log stack to provide a more accurate inventory count. The common rangefinder to be used in this application is the AR3000 distance measurement sensor.

The AR3000 laser sensor uses time-of-flight principles to measure distances up to 300 meters on natural surfaces and is perfectly capable of functioning outdoors. The fast, eye-safe rangefinder is specifically built to measure distances with high precision for surfaces of low reflectance (e. g. asphalt, grass, oxidized steel and aluminum). The IP-67 rated sensor is built with an integrated heater, allowing operation from temperatures of -40F to 140F – without an external enclosure.
