Leica AT402<\/strong> Absolute Laser Tracker is the most portable 3D Absolute Tracker for traditional inspection tasks or for fully guided measurement processes. It is able to be powered by its own internal battery and is able to work in the most demanding environment, yet maintains the highest level of precision and the largest ever work envelope.<\/span><\/p>\n

El Leica<\/strong> AT402 features increased ruggedness and extended battery life. The Leica Absolute Tracker AT402 has a unique \u201cAll in One\u201d system design that incorporates such needed accessories as built-in live video, level to gravity, environmental monitoring and even an integrated IR remote control. By utilizing the integrated WiFi access point functionality the sensor can be used completely wirelessly.<\/span><\/p>\n

The updated Leica<\/strong> AT402 can perform measurements without a warm-up period. This allows the operator to switch the system directly out of the box and start measuring within seconds. The 1.1 firmware also includes such specialized features as \u201cOutdoor Mode\u201d which enhances the performance of the system when using it in adverse conditions like rain or snow. Enhancements also include the use of several reflectors in view of the sensor at the same time.<\/span><\/p>\n

The built-in WiFi on the AT402 can now be used in a company\u2019s encrypted WiFi infrastructure even with several sensors in the same network. Finally, the 1.1 firmware further facilitates the user compensation of the sensor making an already simple task even easier.<\/span><\/p>\n

    Leica AT402 Absolute Key Feature<\/strong><\/span><\/h2>\n

    Portabilidad<\/strong><\/span><\/p>\n

    The measuring system in a minimum set, including the case for transporting and storage, weighs less than 15 kg. Dimensions of the case lets you carry it not only in the car, but even in the luggage compartment of the aircraft.<\/span><\/p>\n

    Working in difficult conditions<\/strong><\/span><\/p>\n

    Due to the tightness of design of the measuring system, regardless certified by IP54 (IEC 60529), Leica laser trackers can operate in harsh environments. The system maintains high accuracy during measurement of the coolant spray conditions, high humidity and dust, near welding and metal-cutting equipment, etc.<\/span><\/p>\n

    Absolute Tracker Leica AT402 – this is the first laser tracker certified for outdoor use, even in rainy weather.<\/span><\/h2>\n

    PowerLock Technology<\/strong><\/span><\/p>\n

    In 2009, the company Leica Geosystems introduced for the first time ever the term PowerLock. PowerLock is a technology based on vision system that provides automatic detection of the reflector and pointing at him a laser beam. The system provides a well-directed hit of the beam, even in a moving target. Moreover the laser beam is directed only to the reflector without affecting the other objects.<\/span><\/p>\n

    Until the introduction of this technology work with the laser tracker, the work has always been complex and obscure for the operator. The operator had to spend excessive time on gaining experience for effective use of the tracker without interrupting the beam. Application of PowerLock technology significantly reduces operator\u00b4s training time and simplifies the tracker.<\/span><\/p>\n

    Wireless concept<\/strong><\/span><\/p>\n

    In order to ensure autonomous power measurement system, is used two identical batteries, one for the power supply of the tracker and the other to power supply of controller. When running on battery tracker is capable of performing measurements during a work shift. With decreasing of battery power to a critical level, the batteries can be replaced both with system shutdown and without disruption. In any case, the laser tracker will carry out its tasks without failures after replacing the battery.<\/span><\/p>\n

    Built-in wireless data interface of Wi-Fi allows you to get rid of connecting cables and this gives full freedom of action for operator.<\/span><\/p>\n

    Measurement of large objects<\/strong><\/span><\/p>\n

    Vision angle of tracker Leica<\/strong> AT402 is full horizontal 360 \u00b0, Vertical – 290 \u00b0. Given the maximum range – 160 meters and high accuracy, can be considered the laser tracker like measurement machine with an incredibly large measuring range.<\/span><\/p>\n

    Volumetric accuracy (Uxyz)<\/strong><\/span><\/p>\n

    Measurement error (Uxyz) is defined as the deviation of the measured coordinates from the nominal coordinates. Fault of measurement depends on the distance between the laser tracker and the measured point.<\/span><\/p>\n

    For absolute laser tracker Leica AT402<\/strong> volumetric fault is \u00b1 15 mm + 6 mm\/m<\/strong>.<\/span><\/p>\n

    All of these errors in the measurements was obtained using the 1.5″ reflector (1.5″ Red Ring Reflectors) in standard mode with test point pace of 2 seconds on measurement point and at stable ambient conditions. Measurements were conducted in the linear range of from 1.5 to 80 m and an angular range of \u00b1 45\u00b0 vertically and 360\u00b0 horizontally.\u00a0<\/strong><\/span><\/p>\n
