A global manufacturer of self-contained drill rigs uses the AccuRange 1000 laser distance sensor to automatically gage the depth of drilled holes. Their drill rigs are equipped with powerful down-the-hole hammers for high-capacity rock drilling in quarries, opencast mines and construction projects. The operator, sitting in a climate-controlled cabin, can know the exact hole depth on a digital console display.
The AR1000 has a nearly concentric optics path to measure down narrow holes. The range is up to 30 meters and the sensor will hold 2 mm of accuracy. Contact Acuity for more information.
