Leica Absolute Tracker AT402

July 13, 2013

Hexagon Metrology released the Leica Absolute Tracker AT402, the next-generation laser tracker based on the Leica AT401 product line. The portable 3D Absolute Tracker can be utilized for fully guided 3D measurement processes, as well as traditional inspection tasks. The new laser tracking system is optimized for ease of use, so operators can focus on the measurement task instead of complicated settings, such as the number of samples or measurement frequency. The Leica AT402 is reportedly ideal for large volume, precision measurement applications performed by industries such aerospace, power generation, heavy equipment and other manufacturers that produce large components and assemblies.

The Leica AT402 introduces a simplified user interface with four pre-defined measurement profiles that adjust the instrument settings to any measurement condition with the click of a button. In addition to its standard mode streamlined for daily operation, users can easily change settings for outdoor measurement jobs and for applications requiring exceptional speed or accuracy. The laser tracker's all-in-one design integrates other usability features, such as IR remote control, environmental monitoring, level to gravity, in addition to powerful standard features such as Leica PowerLock technology, a certified-IP54 rating and built-in WiFi connection for wireless operation.

"The Leica AT402 leverages the groundbreaking innovations of the original laser tracker and introduces significant enhancements for intuitive use," states Eric Hollenbeck, product manager for trackers at Hexagon Metrology Inc. "These refinements help the operator to streamline their measurement work on the factory floor, in the field, or at a remote location, drastically reducing setup time and system monitoring. The lightweight, wireless system has the largest measurement volume in the marketplace, with a maximum measurement volume of 320 meters. This metrology solution is in a class all by itself when it comes to ease-of-use, portability, high precision and the largest-ever work envelope."

The compact measurement system and its case weigh less than 33 lbs. and can be used anywhere, inside or outside, due to its IP54 rating for ingress protection against dust and fluids often found in industrial environments. With a full 8 hours of battery life, the tracker's hot swap batteries enable the operator to install fresh batteries without powering down the system, keeping user productivity high.

The Leica AT402 comes standard with the exclusive Leica PowerLock technology, which automatically finds and locks onto any moving reflector within a field of view of one square meter at a five meter distance. This important feature was a giant leap for the handling of laser trackers. With endless telescope rotation, the AT402 can measure a full 360 degree horizon and a 290 degree vertical dome, resulting in more than twice the measuring volume of conventional trackers, including the ability to measure straight up, which no other tracker can do.
