Laser Tracking Probe for Large-Scale Inspection

Available from Hexagon Metrology, the Leica B-Probe entry-level wireless probing device extends the capability of the Leica Absolute Tracker AT402. According to the company, the probe is intended for manufacturers of large-scale assemblies requiring range, portability and hidden-feature inspection, but only modest accuracy. Designed for inspection, alignment and assembly of large-scale fabrications such as off-highway vehicles, the handheld probe works within a 32.8-ft. (10-m) radial distance of the tracker. It provides accuracy of ±0.008" (0.2 mm) over the full measurement range for greater flexibility than fixed-base stations, the company says, and, using the move-station method, the working range of the system can be easily multiplied with little loss in probing accuracy. The 6.7-oz. (190-g) probe is IP50-certified and powered by AAA batteries. For larger parts or measurements that require higher accuracies, a standard retro reflector can be used in combination with the probe to take advantage of the Absolute Tracker’s 525-ft. (160-m) range.
