HEXAGON MANUFACTURING INTELLIGENCE

Absolute Arm - 7 Axis SE

hpl208scanner

Modular high-end scanning platform.
 
The ROMER Absolute Arm with external scanner is designed for the high performance laser scanner HP-L-20.8 from Hexagon Metrology.

The ROMER Absolute Arm with external scanner is the high-end laser scanning platform designed for the HP-L-20.8 laser scanner from Hexagon Metrology. With HP-L-20.8, the ROMER Absolute Arm offers first-class performance on the most complex surface types. Automatic laser control means that multiple surface colours can be scanned in a single pass. Thanks to the HP-L-20.8’s unique flying dot technology, the scan width and point density are entirely variable, allowing the user to guarantee maximum scan detail where it’s needed most. 
 
All models of the ROMER Absolute Arm are available in three levels of accuracy, allowing you to select the right measuring arm for your application requirements and budget. The 73 Series and 75 Series arms offer excellent price/performance ratios for everyday metrology operations, while the 77 Series – the most accurate ROMER Absolute Arm ever produced – is ideal for specialist or high-end measurement applications.

Increasing productivity across all industries.

Features

RDS
The ROMER proprietary software RDS features SMART technology, allowing total management of checks in the field as well as temperature and shock monitoring.

Laser Scanning
The ROMER Absolute Arm is available with a completely integrated high-performance laser scanner or the external HP-L-20.8 scanner, for complex scanning tasks.
ROMER Absolute Arms are the only scanning systems on the market to offer fully verifiable scanning system accuracy.

Automated & repeatable Probe Recognition
Intelligent Quick Change Probes: Swap touch-probes at any time without the need to recalibrate. The ROMER Absolute Arm’s repeatable mount allows to change probes on the fly, according to your measurement needs.

Instant Feedback
The ROMER Absolute Arm provides immediate acoustic and haptic feedback to the operator, allowing the ROMER Absolute Arm to be used in even the most harsh industrial environments.

Absolute Encoders
Referencing and warm-up time was for yesterday – just switch the arm on and measure.

Measurement Volume
Size does matter: The ROMER Absolute Arm is available in seven lengths between 1.2 m and 4.5 m.

Certification
All ROMER Absolute Arms including scanning systems pass through B89.4.22 certification. Additional certifications according to VDI/VDE 2617-9 are also available. The ROMER Absolute Arm Compact model is available with a choice of ISO 10360-2 or B89.4.22 certification.

Zero G
Zero G counterbalance eliminates torque in the base and arm members, more forgiving of the arm being mounted in a vertical position and puts you in control of the arm.

SmartLock
If the ROMER Absolute Arm is not in use it can be locked safely into its rest position. SmartLock also allows the arm to be fixed in any intermediate position.

Feature Packs
Thanks to easily interchangeable Feature Packs, the functionality of the ROMER Absolute Arm can always be enhanced. Feature packs are available for wi-fi communication, wi-fi scanning capability and full battery operation.

* The Scanning System Accuracy Test most accurately represents the reasonable expectations for machine performance in practical measuring applications while using the laser scanning method. The test consists of measuring a matte grey sphere with 5 different arm articulations. In each articulation of the arm the sphere is scanned from 5 different directions such that the majority of the sphere is scanned. The result is the maximum 3D centre to centre distance of the 5 spheres.
