Common Applications: Acuity AR700 laser distance gauges

The AR700 is Acuity's newest digital triangulation sensor. It's high resolution and fast sampling speeds make it a versatile sensor for many industrial and research applications. As Acuity phases-out the older AR600, the AR700 series will replace it in nearly all applications that demand high-accuracy triangulation sensors.

Lumber measurement
Acuity sensors are used to measure and verify the dimensions of logs and cut lumber. The digital CMOS technology performs well on dark and light colors.

Road Profiling
The AR700-6 or -8 laser measuring sensors with the optional road profiling package is adopted by manufacturers of both "lightweight" and "high speed" road profilers. These vehicular machines are used to measure fine and macro features on road surfaces. The road profiling option from Acuity guarantees high accuracy at high speeds in sunny conditions. The product is commonly used by members of the Road Profiling Users Group.

Steel Mill applications
Steel castings require the measurement of hot, radiating material. This is best performed with non-contact laser sensors. The Acuity sensors excel at this application when equipped with a high-power infrared laser and a narrow band pass filter. Also see the page for hot steel slab width measuring sensors.

Rubber thickness measurements
The AR700-4 (formerly AR600-4) with a 5 mW laser diode is selected by an international reinforced rubber conveyor belt manufacturer to replace existing methods. Acuity sensors perform accurately on black, shiny rubber surfaces.

Concrete block height measurements
Popular architectural pavers are manufactured using a vibrating press. The product is produced on steel pallets. These pallets pass beneath a height measurement system using Acuity laser displacement sensors.

Package dimensioning
Large distribution center use laser systems to measure the dimensions of cardboard boxes traveling down a conveyor. The AR700 laser sensor accurately measures these dimensions which are later verified against known dimensions stored against the parcel's bar code.

Thickness Measurements
Two opposing lasers measure to two sides of a target to report the target's thickness. The benefits of using lasers include high accuracy and non-contact measuring.

Plywood sheet thickness gaging
Sawmills are harsh environments that demand accurate laser sensors under dusty conditions.

Hydroelectric Turbine Clerance and Runout
Engineers select the AR700 laser displacement sensor to measure clerance of a turbine blade relative to the liner.
