ROMER Absolute Arm with integrated scanner

Freedom of movement

Romer-Absolute-Arm-Intergrated-Scanner-M
3D digitizing, 3D modelling, point cloud inspection, reverse engineering, rapid prototyping or copy milling: this system is an all-purpose metrology tool for a multitude of applications.

Freedom of movement: with a fully integrated and certified RS3 laser scanner, this is an all-purpose metrology system for almost any measurement need. Point cloud inspection, product benchmarking, reverse engineering, rapid prototyping, virtual assembly or CNC milling are just some of the typical laser scanning applications that can be added to the rich portfolio of touch-probe measurement applications. The integrated laser scanner is designed to capture data from almost any object surface.

It does not need warm-up time or additional cables and controllers. Scanner and probe measurements are combined in the same software session.

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.

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 comunication, wi-fi scanning capability and full battery operation.

1 The Point Repeatability Test is the reference test to determine measurement arm repeatability with ball probe. The cone is in front of the machine. Points are measured from multiple approach directions. The average point and the deviation of each point to the average center are calculated. The result is the maximum range divided by two.

2 The Volumetric Accuracy Test most accurately represents the reasonable expectations for machine performance in practical measuring applications since it involves measuring a certified length standard many times in several locations and orientations and compares the resultant measurements to the actual length. The Volumetric Length Accuracy Test is the most appropriate test for determining machine accuracy and repeatability. The result is the maximum deviation of the measuring distance less the theoretical length.

3 SI designates the ROMER Absolute Arm with integrated scanner.

4 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 center to center distance of the 5 spheres.

All probing specifications are achieved with a ROMER Absolute Arm mounted on a ROMER base plate or magnetic base and using a 15 mm steel ball probe with a length of 50 mm under stable environmental conditions.

All RS3 scanning specifications are achieved with a ROMER Absolute Arm mounted on a ROMER base plate or magnetic base and a matte grey calibration sphere of 25.4 mm diameter under stable environmental conditions.
