ROMER Absolute Arm

A first in the world of portable measuring arms: The ROMER Absolute Arm features absolute encoders and is therefore the first measuring arm which does not require referencing before measurement. When the arm is turned on, it’s ready to go.

Quality control, inspection, on-machine verification, reverse engineering, virtual assembly or 3D modelling. Wherever these needs arise, you will find the ROMER Absolute Arm. Much more than just a metrology tool, its value lies in its versatility. Portability, stability, light weight and high-performance laser scanners make the ROMER Absolute Arm an all-purpose 3D measurement, analysis and digitising tool that can be used by anyone, anywhere and with minimum training.

Unlike many metrology devices, the ROMER Absolute Arm does not require warm-up time or initialization, thanks to a stable carbon fiber structure and industry leading Absolute encoders. Simply take the measuring arm to the part, switch it on and start measuring.

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.

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.

Features & Benefits

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.
